I have a windows 2008 R2 server running hmail and websitepanel.
Emails from yahoo get bounced stating that emails from our server are not allowed by their policy.
Almost all the emails go to junk folders.
What I want you to conifgure :
SPF/DKIM for all domains and should be setup automatically when I add a new domain in websitepanel
add a limit on email sending of 400 emails per domain per hour.
Add good Spam Protection
