Got a problem here I wanted to see if anyone had ever come across. I have a small insurance company (8 people), the outbound Queue on their exchange server keeps filling up to the point where it stops processing mail. They were getting blacklisted bounceback emails so I figured that it was a virus sending out spam from their network. I found that virus on a PC that they said had virus problems and removed it. I filled out some stuff to get them delisted ,I cleared out the queue, restarted the virtual server and it appeared to be working as of last week. Now today the queue was full again and it wasnt working.
I then checked each PC for the virus and cleaned them all anyway but didn't find anything. The problem keeps happening. There's no way that they sent 22,543 messages to yahoo overnight while there are closed so it looks like either the virus is still there ion some way or there is some other problem. What can I do? Once the queue gets to a certian point it stops sending and recieving legitimate mail.
