iis smtp nntp : pop over smtp

Hello,
I wrote a program, that sends emails under certain circumstances. Therefore
it uses a smtp server that is specified in the programs settings.

Until now this works fine even without pop before I send the new mail but I
have something in my head, that normally it's necessary to receive emails
before I can send new mails. As far as I know this is a limitation that
comes from earlier times where smtp servers did not require authentication.

The servers i tested with did not require pop before smtp. But can I trust
that all other do so or is it still usual to require pop before smtp?

Thanks a lot - Patrick

POP and SMTP are separate protocols and separate servers, and neither
actually cares about the other. Some SMTP servers have a validation
option to validate to the POP account before sending, which is
configurable in most SMTP clients. If you are sending directly to the
server, and the server is not configured to force POP authentication
to send SMTP, then your worries are over. It's only your server that
you're sending through that's an issue, the destination SMTP will
accept it from your SMTP, just not direct from you as a client.
