I'm not sure about the error code message numbers. But it sounds like that
the server wishes to establish that the sender is authorized to send by
forcing you to check for new mail first before sending. I had this problem
once. Did not find any solution (maybe beacuse I use the Chinese program
Foxmail) Nevertheless a quick fix was just changing the SMTP server to
another one not requiring this. Hope this helps.

This feauture is a anti-SPAM configuration apperently.
