>It works fine from my mail client (Netscape 7.1) sending to outgoing mail server "outgoing.verizon.net". Authentication is required. The pop server is mail.verizon.net (to which I can connect fine using wwPop3). I have not tried other products yet, though would consider it if I knew for sure that they would solve my problems (without introducing any new ones, of course!).

I logged into your mail server and it looked fine. It supports basic authentication.

If you want to try one alternative, with zero impact for now, download SMTP Wizard v2.

Run the Compiled VB Example(there is a foxpro example, but the compiled one is good for testing) and enter your mail server, username, and password and try sending yourself a test email.

If it works, then you know SMTP Wizard will work for you. Simple as that, and there is no impact on your current project since you are able to try it outside of your environment.

Good luck!
