From what I have read, this problem is caused by your ISP blocking any E-mail server but their own for outgoing E-mails. From checking in different places on the Internet, this problem seems to be able to be resolved by:
1. Change the outgoing mail server field to SMTP.YourISP.Net/Com. Check your ISP for the precise server name.
2. Change the outgoing mail user name, password to the one you use for your ISP.
3. Uncheck "My server requires authenticion" and then change the settings to enter your ISP's username and password there.
Hope this solves the problem, but if not let us know.
Whereof one cannot speak, thereof one should be silent.
