[cobalt-users] [OT] Email spam

["Andy Clyde, oxfordmusic.net" <andy.clyde@xxxxxxxxxxxxxxx>]

very off-topic i know but if someone could point me in the right place for
an answer i'd be most grateful, otherwise just delete...

one of my clients has had his email hijacked for spam about Viagra. i've
checked our server and it doesn't seem to be coming through us (i ran 'cat
maillog | grep viagra' and nothing showed up, plus our IP does not feature
in the email headers). is there anything we can do about this, or are they
just forging the email header and we have to put up with it. we only found
out coz our client got 1000 bounce back emails this morning.

much obliged

andy
