• 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.

Mail Delivery failing on one server only

coolemail

Basic Pleskian
Please can someone help. We have two servers both with:
OS Linux 2.6.32.28-1.art.x86_64
Panel version 10.2.0

On one, we are able to send emails to [email protected]
On the other one, it fails with:
Jun 16 21:45:50 plesk3 qmail: 1308257150.872860 starting delivery 1581: msg 105971977 to remote [email protected]
Jun 16 21:45:50 plesk3 qmail: 1308257150.915956 delivery 1581: failure: Sorry,_I_couldn't_find_a_mail_exchanger_or_IP_address._(#5.4.4)/
Click to expand...

Can someone tell me what setting will allow these emails to go through?

Many thanks in advance.
