this one has me stumped:

Running Debian 3.1 (Sarge) and the latest releases of Courier-IMAP and Postfix.

Got it all configured, and sent a few test emails, they send from teh server wonderfully, but if i send to it, i never got an error message bounce-back, yet couldnt see them with outlook or squirrelmail

went into webmin, check postnuke user boxes and i have all my test emails there, even tried a few more after that.

Why cant i check email with squirrelmail or outlook?
