• 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.

I am seeing a ton of
Jan 11 12:32:08 srv1 greylist[6983]: SMTP: EHLO: 250 hello
Jan 11 12:32:09 srv1 greylist[6983]: SMTP: MAIL: 250 Mail from <[email protected]>
Jan 11 12:32:10 srv1 greylist[6983]: SMTP: RCPT: 450 Rcpt to <[email protected]> - Temporary local problem - I said try later
Jan 11 12:32:24 srv1 /var/qmail/bin/relaylock[6926]: /var/qmail/bin/relaylock: mail from 78.29.129.246:2236 (not defined)
Jan 11 12:32:24 srv1 greylist[6926]: IP 78.29.129.246 new - temp error
 
As I remember it can be caused by third-party utility which is invoked upon connecting to the server's SMTP service. Try to check following:
# grep greylist /etc/xinetd.d/smtp_psa

There can be something like /var/qmail/bin/greylist
Make sure that it is third-party, but not Plesk package with following command, for example:

# rpm -qf /var/qmail/bin/greylist
qgreylist-0.3-3.el4.art

If it so, just remove /var/qmail/bin/greylist from /etc/xinetd.d/smtp_psa.
It should help.
