We need some assistantce in order to verify and correct some issues that we have with one of our email servers (centos7 installation, ISPConfig on top).
We need to solve:
- check spam settings: gmail has moments when it does not receive emails from this server even if it's not blacklisted on any BL.
- install a dovecot-sieve plugin (duplicates plugin, it removes from queue the same email)
- enforce more strict delivery policy (check MX of the sending domain)
- enable sa_learn option in spamassassin
- Postfix Postgrey setup
