I moved an account yesterday from one server to another. Now the customer, using outlook, can receive mail and can login to webmail and the control panel, but when he sends mail it rejects his password only on send. He is using the same password for pop access and smtp send access, so I am stumped. Why would it reject only when he goes to send? This not a port 25 problem, this is a failed authentication error. Neither server uses the maildir format.
