[oclug] postfix & Rogers

[chris h]

Greets:

Got my personal mail system setup exactly how I want it. 

fetchmail gets mail from various accounts
feeds it to cyrusIMAP with saslauthd 
antivirus and antispam agents filter the mail 
personal IMAP server is accessible via several clients locally and remotely 
and I can turn it on an off as needed without the loss of any mail. 
Webmail and groupware via OpenGroupware.org
postfix sends mails to Rogers SMTP.

This is where is all stops if I user localhost (or FQDN) as the mta 
designation. Postfix fails to authenticate against Rogers as I am not passing 
the credentials properly. 

Question is how do I get postfix to authenticate with Rogers using my existing 
credentials. In short I need to figure out how to configure postfix to use my 
Rogers user and paswd combo to send off the mail. This is the last step..:)
Clues would be greatfully received.

Regards
