I have a perl program that sends email out. It is called from other perl 
programs as well as shell scripts. When run from the command prompt it 
works as expected. However, when it is run from a cron entry and I send 
an email from myself to myself (from user@example.com to 
user@example.com) from my computer I get a 'Relaying not allowed' error 
from the smtp server.

an example:
Sep 28 19:42:56 star1 postfix/smtp[911]: E6DE91BDC2B: 
to=<user@example.com>, relay=mail.example.com[205.178.100.12]:2525, 
delay=0.31, delays=0.05/0/0.21/0.05, dsn=5.0.0, status=bounced (host 
mail.example.com[205.178.100.12] said: 550 Relaying not allowed (in 
reply to MAIL FROM command))

I have talked to the help desk for the smtp server and where I was using 
port 25 they recommended 2525. Where I was using smtp.example.com they 
suggested trying mail.example.com. I have also put specific usernames in 
the sender_relay file as well. None of these changes helped.

I looked through the variables in env and set and no variables seemed to 
be relevant for this problem.

A search of the web and the archive on Postfix has turned up nothing 
even close to my problem.

Some email recipients ISPs will not except direct email. It has to go 
through an acceptable mail server. I assume this means that I have to 
use a rely host.
