Hi Tom. I have been using your software for almost three years now. I'm totally happy with it. However the machine that i was running on crashed and i had to take my original re-programming and rebuild it. The only problem I have is making the mailing function work. Everything is fine except config.email.form.php. I think. I can alter that file and the error messages change so i figured that was the place to start looking. i've been at it for two weeks nows. Help please.

Hi, You generally experience error 501 when the recipient email address has incorrect format. Try other recipients email address and see if it works.
