Re: [cobalt-users] help with logcheck entries



maybe.

but if you cant catch it coming from the outside
then would it be save to assume its originating
from somewhere on the inside and therefor may
lead back to what Gerald said regarding SMTP
lookups, etc. etc. ?

this is a long shot but could one of your users be trying to
send a mail to someone@xxxxxxxxx and its bouncing so its
sitting in the mail queue and retrying every hour or something ?

have u checked queued mail in /home/spool/mqueue ?

sorry i`ve ran out of ideas !
