[Techtalk] Intro & SMTP question...

[Cari]

Hi grrls,

My name is Cari, and I'm new to the list (though I think I know Jen from 
a snowboarding trip. ;)  I've been a programmer forever (mostly Java 
now) and I dabble in IT-type stuff, but I am no linux expert... I mostly 
do things like EDI and integration with applications using Java, so, if 
there are ever any Java-related threads, I'll try to help out the 
community where I can. 

OK, enough about me...  here's my problem:

I have been trying to set up my linux box at home to handle email, ssh, 
and sftp (and a teamspeak server, if you must know.  ;)  I have the 
latter 3 working perfectly, and I can even log in to my IMAP server 
using SSL to access my email... but the problem is that email is not 
being delivered to me!  I'm running postfix and I can telnet to port 25 
from my work computer, which indicates that this is not a firewall 
issue.  I've tried sending manual commands to the SMTP server, but it 
does not respond like I expect... and mail is not being delivered to 
user mailboxes.  

When I attempted to send a test message to my address from my work 
email, it bounces back with a "Host not found." message.

I've googled this to death and I need to get some help!   I hope one of 
you has the answers, or at least can start a thred discussing how to set 
this up properly.

Thanks!
