• 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. If your responses match the persona we are looking for, you'll receive a link to schedule a call at your convenience. We look forward to hearing from you!
  • 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.

Basic Pleskian
Since the last update I am having constant troubles with email accounts when sending or replying to email messages.

This is the message I am getting:-
"error sending your message: Service unavailable - try again later"​

This is our system and the software is the Parellels with Business Manager and stuff.

OS CentOS 6.5 (Final)
Plesk version 12.0.18 Update #10, last updated at Aug 4, 2014 05:00 AM

The system is up-to-date; last checked at Aug 3, 2014 04:44 AM​


This is what the error looks like in the log file located at /usr/local/psa/var/log/maillog
