Hello, I have a problem with my Exchange mail server
A user have the message #550 4.4.7 QUEUE.Expired; message expired ## since thursday on mail with @orange.fr
In the message queue I have this message, the email provider orange.fr tell me that my Ipadress is blacklisted
But when I check on Internet blacklist, I'm not in :
Do you know a solution to resolve this problem ?
and I found that I have a computer infected with cutwail !
now I'll have to find it!
