Hi Chris,
Indeed, that was a typo; it is daemon_smtp_ports. My email client is on
another machine, so I manually typed the config statements.
I added the local_interfaces line as you directed and that solved the
sending issue. Thank you!!
Do you know of a way to specify specific interface:port combinations?
My netstat -plant now has the following:
tcp 0 0 192.168.133.217:7396 0.0.0.0:* LISTEN 28928/exim4
tcp 0 0 127.0.0.1:7396 0.0.0.0:* LISTEN 28928/exim4
tcp 0 0 192.168.133.217:25 0.0.0.0:* LISTEN 28928/exim4
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 28928/exim4
I really only need exim to listen for the web form traffic on 127.0.0.1:7396
and the regular email on 192.168.133.217:25. Any way to restrict listening
to only those two combinations?
Also, I needed to add 127.0.0.1 to my MAIN_RELAY_NETS definition so that
email from the web form will also pass my !hosts = MAIN_RELAY_NETS
statements in some acls.
Do you think that opens me up to outside attackers desiring to use the
server for spam relay, etc? In other words, is it possible for an attacker
to trick exim into thinking that their host is 127.0.0.1 even though they
are on a remote machine? (Assuming of course that they are unable to
actually penetrate the box itself, but rather their masking themselves as
host 127.0.0.1) If so, I do not know of any way to prevent this other than
of course giving up on combining the web server and email server on the same
box.
Thanks again!!
Jeff

Does it really say "stmp" and not "smtp" as it should?

Yes, that's the problem. Do you have a local_interfaces line in your exim
configuration? What command line do you use to start exim (ps auxww | grep
exim).
Cheers, Chris.
