Make sure you know exactly what's required for username and passwords in order to send.

For POP3 logins to SMTP server use the wwPOP3 class to connect with a login, then log off, then just try sending without a username and password through the SMPT class...

>I'm using wwIPstuff’s sendmail()from a VFP app. This has worked fine until I changed my email provider from Earthlink to Verizon. Testing with my email client and talking to Verizon I verified that Verizon requires authentication whereas Earthlink does not. So I added the cUsername and cPassword properties (plus, of course, the new cMailServer property) for Verizon, but sendmail() still failed - giving a 'relay' error. I've read the relevant UT threads on this, plus Rick Strahl's Wiki post (http://www.west-wind.com/wiki/kb.wiki?wc~EmailRelayingDenied), but am still having problems.

>(a) If I must make a POP3 connection first, how would I best do this and can this be done using wwIPstuff? Would I be making a pop3 connection to the smtp server?

>(b) Is it possible that wwIPstuff's sendmail() simply won't work with the Verizon mail server?
