What does this message mean? I have tried googling it but all I get is something about invalid return address so it is putting postmaster infront of it I think. Really not to sure but I am getting alot of these messages all from the same location.

Seems to be a sendmail log, have you checked your maillogs for more details possibly? Are you running a mail server?

I only record mail errors like the one I mentioned above as we have a high volume of email cause we supply our customers with email.

The one email address looks like a spam address. I was hoping someone could tell me what the error message actually means.
