...per campaign with inbox placement that rivals mainstream ESPs while keeping both the domain and the server ownership untraceable to me. Here is what I expect from you: • Register a brand-new domain with full WHOIS privacy and no direct link to my identity. • Provision and harden a VPS (or dedicated) server under equally anonymous credentials. • Install and configure the MTA of your choice—Postfix, PowerMTA, Postal, MailWizz or a comparable stack—optimised for high deliverability. • Generate and publish SPF, DKIM and, if advisable, DMARC records. • Set up reverse DNS, proper HELO, and any other reputation-building tweaks. • Provide a lightweight web interface or API so I can load lists and dispatch campaigns easily. • Su...

...whether OpenDKIM/OpenDMARC are necessary or redundant when using Rspamd, • how you would implement IP/domain assignment and outbound routing, • how you would implement throttling, retries, and sender health monitoring, • how you would handle scheduled sending, forwarding, and configurable retention/deletion rules, • your relevant experience with Linux mail infrastructure, deliverability, Rspamd, Postfix/SMTP • routing, ZoneMTA, or similar tools, • your estimated timeline, • your proposed milestones. Important Note: This project is for lawful email infrastructure, deliverability optimization, sender reputation management, and operational email control. I am not looking for black-hat spam tooling, browser automation, or abusive email systems. Pr...

I need a complete, production-ready email server configured on a Linux host. The exact stack is still open—whether that ends up being Postfix, Zimbra, an Exchange-compatible solution, or another well-supported platform, I’m happy to take your recommendation once you understand my traffic volume and feature needs. What matters most is that, at the end, I have: • A secure SMTP/IMAP/POP environment with SSL/TLS, spam and malware filtering, and DKIM/SPF/DMARC properly tuned. • User, domain, and mailbox management set up so I can easily add or remove accounts without touching the command line each time. • Clear documentation covering every step you took, the location of key config files, and backup/restore procedures. I’ll give you SSH access ...

My production web and email services have been offline since I tweaked a few configuration files on a Centos box. ...Here is what I expect you to handle: • Identify and correct whatever in my recent changes brought the server down • Bring the web service back online (Nginx, virtual hosts, SSL, etc.) • Restore full postfix mail flow so IMAP/SMTP works and queued messages deliver • Harden the server once it is up so the same outage cannot reoccur • Provide a brief summary of the root cause and the exact files you adjusted Acceptance is simple: the website must load publicly, and test emails must send, receive, and authenticate without errors. If you are confident with Linux recovery, DNS, Postfix or Exim, Dovecot, firewalls, and SSL, I’m...

I need a clean, Docker-based email server running on Ubuntu with Dovecot handling IMAP/POP and SMTP relayed through Postfix inside the same stack. The instance must include reliable webmail access—Roundcube or similar is fine as long as it sits in its own container and authenticates against Dovecot. My current platform is GroupOffice. I want every mailbox asset moved across, including messages, folder structures, contacts, calendar items, and the associated files/documents stored in user workspaces. When the job is complete users should log in through the web interface or their usual mail clients and find all historical data intact and searchable. Key deliverables: • Docker Compose (or equivalent) definition with all containers configured • Dovecot fully tuned ...

I have a working installation of Interspire Email Marketer on my Contabo VPS (Ubuntu 22.04 with Plesk). The system is ready but it cannot send any emails. I need an experienced freelancer to configure the local SMTP server (Postfix) so that Interspire can send newsletters directly from my own server – without using any external SMTP provider (no Amazon SES, no SendGrid, no third-party services). What needs to be done: · Review current Postfix configuration on the VPS. · Configure Postfix to allow relaying from localhost () for Interspire. · Adjust Interspire email settings to use local SMTP (localhost:25 or localhost:587 with proper authentication if needed). · Ensure SPF, DKIM, and DMARC records for the domain are correctly set up ...

...better performance and control. The work involves three connected tasks: 1. Domain – Transfer the domain and application out of GoDaddy to EC2, set it up in Route 53, and make sure DNS records propagate smoothly with no noticeable downtime. 2. Email – I’d like mail to live on AWS as well using SES or WorkMail I want it running on an EC2 instance. This means provisioning and hardening the server (Postfix/Dovecot or similar), configuring SPF, DKIM, and DMARC, and confirming that send/receive works without landing in spam. Deliverables • Website live on AWS and reachable through the current domain • Domain fully managed in Route 53 • EC2-based mail server sending and receiving with SPF/DKIM/DMARC passing • Short hand-over guide coverin...

...high-volume outbound threads. • Network & Subnet Mapping: Configure a routed, contiguous /28 IPv4 network block via Netplan. Statically alias the usable IP footprint sequentially to align with our predefined enterprise reverse DNS (rDNS/PTR) naming architecture (ranging from s1 through s14). • MTA & Open-Source Application Stack: Deploy a highly optimized, headless outbound mail transport agent (Postfix) utilizing sender-dependent default transport maps. Bind this transport layer to a standard, open-source open-source marketing automation application base layer running over a hardened LEMP stack. • Telemetry & Logging: Ensure local log-shipping utility configurations are prepared to parse mail transport logs in real time and stream performance metric...

...LTS instance. The core architecture relies entirely on a 100% open-source stack using Postfix and Mautic. The network environment consists of a pristine, completely contiguous /24 subnet block (256 sequential IPv4 addresses) announced via BGP to our bare-metal hardware host anchor. Scope of Work & Key Deliverables: 1. OS Hardening & Network Configuration: o Configure Netplan/network interfaces to cleanly alias and map the entire contiguous 256-IP block. o Harden the Ubuntu 22.04 LTS kernel, optimize network stack performance, flash BBR congestion control, and lift file-descriptor limits (nofile to 65535) to handle intensive parallel SMTP queues. 2. Postfix Multi-IP VirtualMTA Setup: o Configure Postfix sender-dependent default transport maps to system...

I need a clean Postfix installation configured to handle both outgoing and incoming mail. All account, alias, and domain information must live in PostgreSQL, so the build has to include the proper SQL maps and permissions from the start. My goals are straightforward: – Mail flows reliably in both directions. – TLS is enforced for all SMTP traffic. – Users authenticate against the PostgreSQL-backed tables. – Standard anti-spam and DKIM/SPF records are in place so messages land in the inbox, not junk. You are free to choose the Linux distribution you’re most comfortable with, but please document every package, file path, and command so I can replicate the setup later if needed. Once the server passes basic send/receive, DKIM/SPF, and relay-restriction t...

I need a Postfix-based mailserver configured so our team can reliably send and receive email. Security is paramount, so the build must include SMTP AUTH, TLS/SSL, and STARTTLS throughout. Mailboxes will be accessed over IMAP only; no POP3 is required. Here is what I expect: • Install and configure Postfix on a Linux host of my choosing. • Enable and verify SMTP AUTH, TLS/SSL, and STARTTLS for all connections. • Integrate an IMAP service (such as Dovecot) and align it with the Postfix user database. • Harden the server with sensible defaults—SPF, DKIM, basic rate-limiting, and anti-relay measures. • Provide concise documentation that shows key config files, how to add new domains/users, and how to back up the settings. I’ll...

I need a single, reliable inbox set up on my existing DigitalOcean droplet so that our clients can start writing to us directly. The domain is already live and pointing to the droplet; all that’s missing is a properly configured mail stack. I’m flexible on the underlying software—Postfix, Exim, Dovecot, or a sensible combination—so feel free to propose the stack you’re most comfortable hardening and supporting. Security (TLS), clean DNS records (MX, SPF, DKIM, DMARC) and straightforward logging are critical, but the overall footprint should stay light since we only require one mailbox for now. Deliverables • Install and configure the chosen mail server stack on the droplet • Update DNS to route mail through the new inbox with validated S...

I ...many full inboxes as I like under my own domain, strictly for internal company use. I will be creating each mailbox myself, so the focus is on providing the underlying configuration and a clean Roundcube webmail interface where every new account automatically has its own secure password and can both send and receive without issues. Here’s what I expect: • Install and configure the mail stack (Postfix/Dovecot or comparable) on my VPS or cPanel server so it supports unlimited mailboxes on the domain. • Deploy Roundcube, theme it lightly with my logo, and make sure each mailbox can log in independently via HTTPS. • Set DNS (MX, SPF, DKIM, DMARC) for solid deliverability. • Document, step-by-step, how I can manually add or delete accounts and rese...

...stack must comfortably run anything from plain HTML to PHP-driven WordPress and full e-commerce builds, so current versions of Apache or Nginx, multiple PHP versions, and MariaDB/MySQL are expected. Email has to be part of the same box. I am leaning toward a Roundcube or Cosmos webmail front-end, but I am open to a better suggestion if you can justify it. Under the hood, please wire up a solid Postfix/Dovecot combination with SPF, DKIM, and DMARC so outgoing mail lands in the inbox and not spam. Deliverables • Latest LTS Ubuntu installed, updated, and secured (UFW and basic hardening) • Webmin/Virtualmin configured over HTTPS, ready for virtual-host creation • Web stack (Apache or Nginx, PHP-FPM, MariaDB/MySQL) tuned for performance • Let’s Enc...

I need a complete, self-hosted email solution for a small business that I’ll be running on a Linux server (Ubuntu or CentOS—whichever you feel is best for the chosen stack). The key objective is to move away from third-party providers and gain full control over our mail, security, and data compliance. The specific mail-transfer agent is still open: Postfix, Exim, Mailcow or another proven alternative can be used, as long as the end result is stable, secure, and straightforward to maintain. What I expect from you: • A production-ready mail server configured with SMTP, IMAP/POP3, spam and virus filtering, DKIM, SPF, DMARC, and valid SSL/TLS certificates. • Simple webmail access and clear instructions so that I can add domains, users, and aliases without t...

I have a clean Linux server waiting for a full Horde Groupware Webmail Edition deployment. Your task is to turn that box into a production-ready mail system, complete with secure web access, working SMTP/IMAP services, and a short hand-over guide. Key deliverables • Horde Groupware Webmail Edition installed and reachable over HTTPS • MTA (Postfix or Exim—your call) and IMAP/POP service configured, spam-free mail flow verified with external inboxes • SSL/TLS certificate in place (Let’s Encrypt is fine) • One test domain and mailbox created, end-to-end send/receive confirmed • Brief documentation of the steps and configs applied I will supply the distro details, DNS records, and root credentials once we agree on timing. Success is a s...

I have a freshly-provisioned VPS that needs to handle all of my domain’s email. The core job is to turn this blank server into a fully functioning mail system that can send and receive reliably while passing modern deliverability checks. Here’s what I need done: • Install and configure the mail transfer and delivery stack on the VPS (Postfix/Dovecot or an equivalent, as long as it is stable and well-documented). • Enable secure access over SMTP, IMAP and POP3 with valid TLS certificates. • Create the first mailboxes and aliases, confirm they work from common clients such as Outlook, Gmail (via external POP/IMAP), and Thunderbird. • Set up DNS records—SPF, DKIM, DMARC and the appropriate A/MX entries—so that test messages land in ...

If you already run your own servers or have experience with tools like Postfix, PowerMTA, MailWizz, Sendy, or Amazon SES, let me know—anything that makes hitting volume without throttling or blacklisting easier. Reliability and transparency are more important to me than fancy dashboards; as long as the campaigns go out on time and the metrics look healthy, we’re good. Please outline the approach you’d use, the platform or software...

...MailWizz installed, secured, and made ready for production mail-outs. You’ll handle everything from uploading the script to applying best-practice server tweaks so the platform runs smoothly and inbox delivery starts off on the right foot. The VPS is completely under my control, so you’re free to tune PHP, MySQL/MariaDB, and the web server of your choice. I’m open to whichever MTA you recommend (Postfix, Exim, etc.) as long as it pairs reliably with MailWizz and supports DKIM, SPF, DMARC and bounce/feedback loop processing. Deliverables I expect: • Fresh MailWizz installation with all required PHP extensions enabled • Optimised server configuration, cron jobs, and queue settings • Proper domain-level authentication (SPF, DKIM, DMARC) and bou...

...so I can send only transactional emails such as order confirmations and password-reset links from my application. SSL/TLS encryption is mandatory; every connection to the server must negotiate a secure channel before any message is accepted. I already have a VPS and a dedicated domain ready to point wherever you ask. Your work should cover the full chain of deliverability: installing the MTA (Postfix, Exim, or whichever stack you prefer), generating and applying SSL certificates, and setting up SPF, DKIM, and DMARC records so common providers do not flag the messages as spam. Once everything is in place, send a live test from a sandbox account and show the headers hitting inbox with a clean score.

My Magento store was migrated to a Hostinger VPS and, ever since the move, no “Order Confirmation” messages reach customers or my own business inbox. I’m routing mail through a third-party provider such as Gmail/SendGrid, but I’m unsure whether the settings were carried over correctly during the migration, or whether something deeper in Magento, postfix/Exim or the VPS firewall is blocking outbound traffic. Or is an SMTP issue where a free extension needs to be added to Magento? Hostinger support has already reviewed their side; I can forward the full chat transcript for context. What I need now is a clean, provable fix inside Magento and on the server so every new order triggers a confirmation email without fail. Acceptance criteria • Order placemen...

...email confirmation are both fine, so choose whichever combination gets us approved fastest. • Configure production-ready sending limits and the correct sending pool to sustain the 50 k-per-day volume without throttling. • Build the required IAM policies, SMTP credentials and verified identities, then walk me through where to store them safely. • Set up the SMTP endpoint and show me sample cURL / Postfix / Node or PHP snippets so I can trigger campaigns directly through the SES SMTP API. • Apply essential deliverability best practices: SPF, DKIM, DMARC, feedback loops, dedicated IP (if needed), and relevant sending rate adjustments. I don’t need integrations beyond AWS SES itself—once the SMTP endpoint is live and tested, I’ll plug it into my...

Gmail keeps bouncing my messages with the dreaded “550-5.7.26 This mail is unauthenticated” notice. I send through a Postfix server and manage all DNS zones inside DigitalOcean’s control panel. I already know the problem: my domain lacks working SPF and DKIM records. I need an expert who can generate the correct tokens, publish them in DigitalOcean DNS, and tie everything back into Postfix so Gmail finally recognises the messages as authenticated. Scope of work • Create or repair one SPF record that aligns with my current sending path. • Generate a DKIM key pair, add the TXT record in DigitalOcean, and wire it up to Postfix (OpenDKIM or equivalent). • Verify both records with common testing tools (Google Postmaster, dig, etc.)...

My production mail server runs on Debian and every main layer—Postfix, Zimbra and the Kernel—now needs to move to the latest stable releases. All three components must come through the process with complete data integrity, so the job starts with a solid backup plan: at the moment no backup exists and I will rely on you to design, create and test one before any package is touched. Once the safety net is in place, the work continues with a carefully staged upgrade. Postfix, Zimbra and the Kernel should be brought up to date, followed by migration to the current Debian stable. I expect minimal downtime, full preservation of mailboxes, calendars, contacts, aliases and logs, and a short verification window after each major step to catch issues early. The assignment i...
