1. Open up Mail.app and press Command+Comma to invoke the Preferences window.
2. Switch to the "Accounts" pane and press the + button in the lower-left corner.
3. Under "Account Information", fill out the following information:
   • Account Type: POP or IMAP (we recommend IMAP)
   • Email Address: email-name@your-domain-name.com
   • Incoming Mail Server: mail.your-domain-name.com
   • Username: email-name@your-domain-name.com
   • Password: your email password
   • Note that POP uses port 110 and IMAP uses port 143
4. Select "Add Server..." from the Outgoing Mail Server (SMTP) pop-up menu. Here are the details for it:
   • Outgoing Mail Server: mail.your-domain-name.com
   • Server port: 26
   • Use Secure Sockets Layer (SSL): NO
   • Authentication: password
   • User Name: email-name@your-domain-name.com
   • Password: your email password
   • Dismiss the window by pressing "OK."
5. Back in the "Accounts" pane, switch to the "Advanced" tab and do not check the box marked "Use SSL" towards the bottom.

What is the imap path prefix?

The correct code is INBOX (all caps).

Too many connections, 500 errors? Here is a fix.

Thunderbird is normally the route I suggest, however the main problem with Mac Mail I've seen is with the IDLE setting, basically this leaves the connection to the server open to check for new messages as soon as they arrive rather than trying to connect every say 5 minutes or so.

NOTE: Before this fix will work, you may need to kill your hanging processes. You can simply ask Notable Web to kill all of your current processes.

This link describes the setting and how to change it in Mac Mail: http://email.about.com/od/macosxmail..._imap_idle.htm
