I have two Exchange 2K3 servers running on 2003 servers. No FE\BE config at all. The problem is I am getting flooded with junk on my first email SMTP queue. There is nothing hitting my second? All email functions are fine in and out. I found when I turn off the Exchange MTA Stacks Service all email is fine and there is no more flooding. I have my Virtual Server set up as follows
Both have the same on Authentication, Connection and Relay
All options are checked
All but the list below
List is empty
Only the listed below.
My domain is listed in the list as Granted.
What am I doing wrong?
