Help Me
 

I am working on setting up a mail server on RHEL 4. I am using postfix and squirrelmail. i am trying to retrieve users from my 2003 ADS. and i can able to do so. i can able to log in through squirrelmail. i am receiving mails too. but the problem is cant able to send mail to anybody fromn any users. receiveing error code 111. Any help pls?????????

please use better thread titles in future, this is a help forum. the fact that you want help is a given. something like "help with sending mail via postifx" would be much more useful...

you need to provide more useful information about this setup. where are you trying to send mail to? is it a different domain or something? generally if this is a little box inside and AD infrastructure you'd use the smtp address for your exchange environmant as the default relay in postfix, .e.g "relayhost = my.exchange.server.com"
