Hi all, I've exch 2k and I installed Trend Viruswall on my server. The issue is that I can't send mail using POP3, it give me "relaying denied". On virtual smtp the authentication is default and also on POP#. I also checked on Outlook at Accounts-- My outgoing server requires authentication and also I checked ---Log on to incoming mail server before send mail. What can be the problem ???? On Trend VirusWall I have nothing about POP3 so I don't see where is the problem. Please help me. Thanks in advance --------------------------------- Do you Yahoo!?
