Then I am completely confused why you feel the need to create your own SMTP client. The WebCat emailer is a simple SMTP client that reads a text file and performs the bare minimum SMTP transaction to hand off to a full MTA. I suspect that what would really help you is to do some preliminary checking of the e-mail address before transmitting, which would solve most of the problems that emailer will have. Another thing to consider is that the FROM: should _never_ be user definable; it should only be set by the system to a known value. This doesn't prevent a webmail app from using some other e-mail address for FROM:, but you need to get that from the user profile. It does prevent spammers from using your site to send out their swill (and they will, if you don't prevent it).
