Something else must be wrong. The question is with what settings. There are hundreds of combinations of Port x unencrypted|StartTLS|TLS x authentication method. The port 465 was intended for TLS, then it was depreciated. Then they introduced other ports. Legacy mail servers pissed that all on etc. From experience, getting a SMTP client working is real pain. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
