Subject: Re: [exim] Yet another "Relay Not Permitted" & log file interpretation
I don't mind posting the file. I was just so huge, I thought maybe the log
entries would indicate what the differences are. The autoconfigure file
follows, but first (here at the top) another difference between these two:
user2 (the one that works) also has a user login account on this host, while
user1 doesn't.

And, another question: in the debug command line you suggested, where did the
IP address come from? I thought about that, but this machine is behind a
firewall and uses DHCP, so I didn't know what host address to use.

And now, without further ado, the configuration is pasted below Dave's reply-
