  Configuring sendmail on Jaguar
Subject:   Outgoing mail not... going.

This article was the best! I'm an idiot and now I've got my very own mail server. YEHAW! Anyway, to my question:

I'm using my Airport Base Station as a router to handle internet access for my Macs at home. The other Macs are wired and log into my G4 to get mail. I have no problems sending mail to any local account, however, when I try to send email outside (using my system as the outgoing mail server) the message never gets delivered. I've included the 'Behind a firewall' and 'Lame ISP' lines in the config.mc file, but no go.

Any clues?

    Where does the message go? Does it just stay in the queue on your mailserver.

    Check the /var/log/mail.log file for clues.

    Also, check to see that you can connect with your SMART_HOST by telnetting to port 25 from your mail server.

      Thanks for your help. One thing I should mention is that when I use mail.mindspring.com as my outgoing mail server in Mail.app, all works fine (EarthLink is my ISP).

      I get an appropriate response using telnet as described in the 'Setting up a Site Server' article. This is with the SMART_HOST definition.

      I checked out the log file and here's what I get (usernames and system names removed to protect the innocent): I am sending mail using localhost as the outgoing mailserver:
