It sounds more of a problem with your email server. Have you tried
checking the Event Log to see if any warnings/errors are listed?

Thanks,

I had a similar issue, talked to support and they were blocking SMTP
messages. Issue was fixed on their end by unblocking these types of messages
so end result was the code worked fine. So you might check with who is
admin'ing your mail server(s) for similar issues.

Maybe your SMTP server demands user authentication? Check this out and
rebuild code.

Yeah, that's most likely. If he could send to any old address without
authentication, the mailserver would theoretically be open for relaying
