I'm confused by the sending process.

I set it up so I get postmaster routed to my mail account. And I get system messages, but if I try to send to the same system account directly it bounces, and the postmaster gests the bounce which of course is the same system account.

I didn't see instructions to create a system mail account but I did the following:

as the user I did "maildirmake $HOME/Maildir"

I created a "locals" file just to make sure, in it I have :

localhost barcelona barcelona.drgutah.com

Also in smtpaccess/default I added the following to add internal IP's that we use. I'm assuming the below is the correct format to let an entire IP range though.

10.200.1 allow,RELAYCLIENT 10.200.2 allow,RELAYCLIENT 10.200.3 allow,RELAYCLIENT 10.200.4 allow,RELAYCLIENT 127.0.0 allow,RELAYCLIENT 209.180.81 allow,RELAYCLIENT

When I try using a client inside my network to send a message though my client I get:

The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'kpettit@barcelona'. Subject 'test', Account: 'barcelona', Server: 'barcelona', Protocol: SMTP, Server Response: '517 Syntax error.', Port: 25, Secure(SSL): No, Server Error: 517, Error Number: 0x800CCC78"

POP is working though, so I can get system message when they go though and I can send message though /usr/sbin/sendmail (coppied from courier/bin/sendmail). But that's about all I can seem to get working right now.

Thanks for any help,

Keith
