The POP server, SMTP server, port numbers, SSL enabled, settings are all identical for both domains. However, my
rameshb@knomadix.com set up works fine. But my
rameshb@ultimeta.com set up fails to authenticate. BTW, the passwords are also same for both accounts and have been typed correctly. I am getting the same problem when I try to set up IMAP server settings on my iPhone. The Knomadix account works but the ultimeta account does not work.
