easiest way is to edit the "inc_mail.asp" file to include the username/password. keep in mind that all of the SMTP providers used by Snitz don't support usernmae/password so you may to use one that would require a new software purchase. That's what happened to us.
Thanks for the help but after looking at the file inc_mail.asp, I have no idea where I enter these details. Sorry but I have no ASP programming skills at all.
Does anybody know if a mod has been done for this. It might make it a bit easier for me. If not could somebody give me a some more help
