"qq internal bug" in qmail

[bartu]

Hi,

since yesterday i have a huge problem with qmail. I stopped accepting mail and sends error message like this "451 qq internal bug (#4.3.0)".
I sill can send emails through webmail engine (horde).
After doing some reserch i've found out that it can the issue with qmail-smtpd process, becouse sending mail with qmail-inject process works fine (i suippose that horde uses it).
I've already tried solution for the forum:
http://forum.swsoft.com/showthread.php?t=51390
but it gives just other error message "qq read error"
Also i've run dpkg -i on some .deb packages from apt archive cache like: psa-qmail, psa-drweb and tried installing older versions of psa-qmail but with no luck.
My system is a centralized mail server running on ubuntu

qmail-queue-handlers[13643]: possible qmail-smtpd exited by timeout, reset connection or with "See http://pobox.com/~djb/docs/smtplf.html"

this is not related to plesk, there is issue with mail server that sends mails to your server.

here the detailed explanation:

http://cr.yp.to/docs/smtplf.html

there is nothing to do with Plesk qmail, fix should be applied to remote mail server.

but Plesk qmail notify you about this
