I have Courier-IMAP running along with Squirrelmail Webmail and Postfix. Postfix is delivering messages just fine and Squirrelmail does not appear to have any problems. However, when I connect using a third part client such as Outlook or from my Motorola Q, I have a small problem. The email account is established as an IMAP account. The account will successfully download emails from the server and will send email as well. However, when emails are deleted from the remote account, they are not deleted from the server. I am guessing it is a permissions problem, but I don't know where to begin. All of my Postfix related stuff runs under virtual:virtual. I would appreciate any help to get me pointed in the right direction.
