  • 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.

Postfix SMTP sending error

matt.simpson

Basic Pleskian
Stumped at this one... I'm at 11.0.9 Update #13 which is running Postfix. I am unable to send mail. Not sure which update caused this, but it's one of the more recent ones.

In /usr/local/psa/var/log/maillog I see:
Sep 19 12:36:28 web01 postfix/qmgr[3134]: warning: connect to transport private/10.1.16.140-: Connection refused

Which results in:
Sep 19 12:36:28 web01 postfix/error[3219]: 2F24F240500: to=<email@address.ca.ca>, relay=none, delay=0.2, delays=0.17/0/0/0.03, dsn=4.3.0, status=deferred (mail transport unavailable)

Any ideas?

Quickest solution to such problems is Install QMail with the auto-installer and then back to postfix. However looking at the errors, looks like a firewall or resolution problem ...

Please check that you dont have a firewall blocking outgoing port 25 + and your server resolvers are working pretty fine too.
 
Thanks abdi, I actually just switched from Postfix back to QMail... and I'm not switching back. That sort of sounds like a pretty big problem if an MU kills SMTP service, but anyways. Thanks for the heads up.
