I have an account on Gmail. I want to be able to send messages from my other address (info(at)[login to view URL]) from the Gmail account. I'm trying to set it up, but I get an error saying:
Authentication failed. Please check your username/password. [Server response: 334 PDY4ODM2OTkwOS40Mzg0NDY3QHZwczI3NDcyOC5vdmgubmV0Pg== code(334) ]
Please for help.
