<sigh> ... well, I'll pull out the Stevens network programming book tonight. I guess I could use Perl, but this seems like a good opportunity to get a firmet grip on C. My clients will never use only one email program ... we're an ISP. I see a lot of Netscape, IE, Exchange ... blech. Thinking further on this, I see delivery will have to be looked into ... each user still needs a unique mailbox.
