• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

possibly qmail-smtpd exited by timeout, reset connection. How to set QMail timeout?

QMail errors in mail log. possibly qmail-smtpd exited by timeout, reset connection

***Edited***

I found out that this wasn't a timeout issue and that it was the following as is now fixed:

I had a few "possibly qmail-smtpd exited by timeout, reset connection" messages in my mail logs after switching MTAs to QMail.

At the end of that messages it says see "http://pobox.com/~djb/docs/smtplf.html".

This is an issue where QMail is receiving messages with bare LFs (line feeds) which is not allowed as stated in RFC 2821, so it is the fault of the sending server, not QMail.

Basically the sending server should fix their problem, but we can't really force this issue so there is a work around by using fixcrio.

And thread: http://forum.parallels.com/showthread.php?t=94222

Once you get fixcrio up and working then you won't receive any more messages like that in the logs.

Cheers.
