In a nutshell: my machine can send out mail fine, and it can send and
receive mail to and from itself, but it has never been able to receive
mail from the outside. It appears that my host rejects all mail from
the outside, with the message: "550 relaying to <user@123.456.789.012>
prohibited by administrator (in reply to RCPT TO command)".
How can I begin to troubleshoot this problem?
What follows is my best guess on what would be useful information
to diagnose the problem (I'm very green at this; please let me know
if I've missed some important piece of information).
My OS is Linux; my distribution is Debian 3.0; my kernel is
2.4.18-686. I configured exim with eximconfig. I quote the entire
exim.conf (minus comments) at the end of this post. The exim demon is
properly started at boot time. The output of netstat -tlnp is:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 583/exim
I can ping my host from the outside and I can connect to it via ssh.
Thanks in advance,
-Irv

PPS: Here's my exim.conf file. I've removed the commented lines and
changed the name of my domain to "secret.enigma.com", for security
reasons. Aside from this, it is in its original form (I assume it was
generated by eximconfig):
