>I think part of my problem was that i had installed the latest 4.40 copy of WWC (with the wwipstuff) on a PC running VFP8. I then tried to add emailing capabilities to a PC with a VFP6 app. I was copying files from the VFP8 PC to my VFP6 pc to see if it handled authentication (unlike IDSmail, which does not). I had encountered some non-bracketed code in the SENDMAIL method that was expecting VFP7or8. I think i got past that.

Using someones smtp server, acctname, and pw where authentication is performed, VFP hangs on SENDMAIL. If i use my own smtp server (no auth), i can send email. Am waiting for these "auth" users to try it on their end.

I've had the same problem with IDSmail years ago - the user wanted us to send automatic mail on their behalf using our SMTP server, and of course the only way to do that was to allow relaying on our server, which would open the gate to all spammers. I tried doing the same using wwIpStuff then, but ran into the same problem - and we ran an Exchange server, whichever version of it was current anno 2000.

Seeing that you're in the same area as I am - I also had to switch from Earthlink to Verizon. Some time around October or so, Earthlink told me they now have DSL over Verizon's land lines; with all the other trouble I'm having with Verizon (just go through their website a few times, try to pay your bill online, you'll see) I'm seriously thinking of switching back. Never had a problem with Earthlink.
