Most Internet Service Providers restrict access to their outgoing mail servers to prevent SPAM from being sent through their mail servers. If you are getting the "550 Relay Denied" error message, the outgoing mail server cannot verify who you are and will not allow you to send mail.
If you connect to the mail server for "domain.com" it may only allow you to send mail that is from "username@domain.com" -- if you try to send from another account and have the return address of "username@anotherdomain.com" it may restrict you from relaying to another server For example, if you connect to the internet using domain.com, it will check to make sure that your email says it's from domain.com . To fix this, change the "From" field under Tools: Options and make sure that your Return Address matches.
