Can someone help me, this is driving me nuts!
I currently run sendmail on port 25, I have had a requirement to install smtp_auth, which all works fine. However I now find out that one of my users ISP's blocks port 25 so he can't access the mail anyway.
The answer? NAT port 10025 or what ever to port 25.
Whilst this doesn't answer your question, is there any particular reason you didn't just open port 587 in your firewall and use the MSA, which sendmail runs by default for this very purpose?
