>I'm looking for a reliable SMTP Server control. It's not a SMTP control to compose and send emails (I already use SEE4FP from MarshallSoft), but the server side of the SMTP equation. My problem arises when the user wants to send multiple emails and his SMTP server blocks his account due to anti-spam restrictions (even if the emails are legitimate).

You can write your own server very easily. To convert your SMTP component into a mail server, you simply need to add the MX lookup capabilities.

i.e.
Use an MX lookup on the recipients address domain, then use the smtp component to send the email directly with their server. No authentication is ever needed for a local account recipient.
