Courier IMAP Relay access denied sending

[unclecameron]

I am using the Debian Etch/mysql/postfix virtual howto, and everything works fine except when I attempt to send mail only from a webmail IMAP client (Roundcube), and the mail.log file says Relay access denied, but only when sending to a remote domain, it works with other local virtual domains. The same account will Pop3 fine to both local and remote.

Sould I be looking at Courier-imap, Postfix or Authdaemonrc somewhere? Why would Postfix think Courier-imap isn't legitimate (and only to remote domains) but Courier-pop3d is?

Thanks,

Does it work with a normal email client such as Outlook or Thunderbird? If so, it must be a Roundcube setting.
