Yes. > Can you foresee any problems? Several. The first one is you didn't read the archives or look for pre-existing code to talk to SMTP directly. :-) Manuel's upperdesign.com has one, and there are plenty of others. You could roll your own -- I did, so it can't be too tricky. :-) Also, at that volume, I think you're going to run into trouble just in talking to the all the SMTP servers. I *BELIEVE* one major speed-up can be achieved by sorting the outgoing emails by their recipient's domains... You may want to research how "real" mailing list software deals with this if you actually expect to hit 100K addresses. If they're all the same email, you'd be *WAY* better off just interfacing to majordomo, ezmlm, SmartList, or whatever other mailing list software was designed to handle this. -- WARNING richard@zend.com address is an endangered species -- Use ceo@l-i-e.com Wanna help me out?
