Postie works well with GoDaddy hosting, but you are required to use GoDaddy mail servers (rather than something like Gmail).

Create a new email address through the Cpanel functions in GoDaddy. After the email is created go to the Configure button that showed multiple ways to auto configure the email for many other hosts. At the bottom of the page it shows Manual Setup. This is for Postie.

When you enter the MailServer in Postie be sure to use the full server name: a2plcpnlxxxx.prod.iad2.secureserver.net (The xxxx will vary depending on your account)

Mail Server Settings

• Protocol: POP3
• Use Transport Layer Security: No
• Server: a2plcpnlxxxx.prod.iad2.secureserver.net
• Port: 110
• Userid: your full email address
• Password: your password
