We can verify from the trace that your mail server is being logged into, but the message is not transmitted properly. Any chance you could check your mail server logs for issues? Do any other devices in your network relay through this SMTP server without problems?

The smtp server email method is not working via the GUI.
I had to use the php mail.
Pls close the thread.

Thanx a lot for your help.
