Unable to get sender domain by sender mailname

[P_heck]

Hello,

Pleask Version 11.0.9-debian6.0.build110120608.16

Since May, 12, I receive the following messages in my logfile:

May 23 09:11:30 ph-internet /usr/lib/plesk-9.0/psa-pc-remote[13271]: Unable to get sender domain by sender mailname

This msg. shows up not on any incomming mail, but only on some of them. It didn't happen before May 12 (checked old logs) and I haven't done any change on the system (only a Plesk update was automatically deployed some days before).

Does anyone have any idea, under which circumstances this message is written and maybe, how I can get rid of it?

I didn't see any problems in mail delivery, but I am always getting nervous, when errors are written in the log, I can't explain.

Thanks for your feedback!

Peter

Don't be too nervous, P_heck

This means that Postfix milter (mail filter) encountered an email sender address in short form (without domain part or '@' sign). Since this is not supported under Postfix, such requests cannot be processed.

If you're still nervous, try to track down mail messages that cause this.
