• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service. If you'd like to be part of the discovery process and share your experiences, we invite you to complete this short screening survey.

  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Qmail and Postfix Issues

Jeff Knapp

New Pleskian
I am running 10.4.4 MU#20 on CentOS 5.

I was previously using Qmail, but had problems with the queue holding outgoing emails for 1-4 hours, sometimes even longer. Some messages would send right away, but the majority would get deferred and hold for long periods of time.

Decided to switch to Postfix. Everything appears to be working properly, but I am getting complaints about rejected emails. The rejection only happens from external email addresses and only when the message is a forward from another email. I have SPF and domain keys turned off, but spam and antivirus running. If I turn off all email protection, the messages come through, but this isn't a fix as I need the spam filtering. I am also using zen.spamhause.org blacklist.

Any ideas?

Jeff
