• 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.

user quotas with postfix

galaxy

Regular Pleskian
I need to move to postfix instead of qmail for a variety of reasons I won't go into here.

In my testing, I've setup a demo plesk 9.0.1 instance with postfix. I'm testing out user quotas.

In the old qmail configuration, when you sent mail that would put the user over quota, it would bounce the message back to the sender with an error stating the recipient mailbox is over quota. I want to preserve this functionality.

When testing plesk with postfix, the mail is absorbed into the postfix queue and gives success back to the sender SMTP, however postfix never delivers it to the recipient. Instead it logs a deferral line:

Apr 16 12:45:57 plesktest postfix/pipe[9410]: D6B35DCF8012: to=<bk@???????.com>, relay=plesk_virtual, delay=242, delays=240/0.01/0/2.3, dsn=4.2.1, status=deferred (Message can not be delivered at this time )

and when you run mailq, it shows the message status "Message can not be delivered at this time". It remains in the queue for days.

I can just hear it from my users since the sender sees success and the recipient never gets it, nor any warning/error messages.

How can I get it to work like it did with qmail and bounce the message?
