Hi Pascal,

You're still misunderstanding me. There is no SMTP server on the client
machine, any more than there is a Web Server. The SMTP Server is on the web
server, or another server having an SMTP server is used.

Your problem is probably due to the configuration of the SMTP server on your
server. If, for example, you are attempting to send an email in which the
"From" domain is not the same domain as the server's domain, and the server
doesn't allow relaying (most do not, as this is typically used by SPAMMERs),
the email will not be sent.
