Spammers in my SMTP Virtual Server Current Sessions
Posted on 2009-04-29
Windows SBS 2003 SP2 and Exchange 2003 SP2.
I am using AntiGen for SMTP servers.
After making sure i was not listed in a black list@ mxtoolbox.com, i have decided to enforce security on my exchange server.
I have made sure I was not open to relay.
In the Virtual Server i checked: Anonymous, Basic authentication and Widows Authentication.
Though, in the Relay section i have Checked : Only the List Below, this list is empty. I also left "Allow Computers..." Unchecked.
Even with those settings, i sometimes find spammers connected to my SMTP (Current Sessions). Is this normal? Are these spammers will be blocked by antigen, or I am relaying spam??
Thanks for reading, and I am sorry for my english is not perfect. :) I am French Canadian.
