Alert Level 2 qmail errors

[laughingbuddha]

Hi,

I keep seeing this type of alert email every now and then. What is it?

I've censored out my users domain and my servers domain.

Code: Select all

Received From: s1->/var/log/psa/maillog
Rule: 1002 fired (level 2) -> "Unknown problem somewhere in the system."
Portion of the log(s):

Nov 11 22:58:46 s1 qmail-scanner[30709]: Clear:RC:0(212.159.7.99):SA:0(-2.1/5.0): 0.728626 4749 david.kidd@tcp.co.uk nigel@[removed].com Username_Error <007e01cb81f3$f9a70620$ecf51260$@kidd@tcp.co.uk> 1289516325.30711-1.s1.[removed - my server].net:2699 1289516325.30711-0.s1.[removed - my server].net:161 orig-s1.[removed - my server].net128951632579030709:4749

Is this anything to be worried about, or is it a bounced email? My users email address does exist as an alias of his email account.

I don't get loads of these sort of emails a day, but they do come in, around 3 a day every other day.

Thanks,

Matt
