Oh dear, I appear to have killed your cat or something with my message.  I apologize. The distinction I was making -- apparently not well enough for you to understand -- was that in SMTP, there is usually minimal conversation; the conversation is, in 99% of cases, the same between the two partners, and the task is a batch-like, bulk task usually involving one transaction. By comparison, POP/IMAP are chatty, and they tend to stay connected for multiple discrete 'transactions'.  This is more 'peer'-like behavior, a la Jabber, etc. There isn't a hard-and-fast definition of what a server is and what a client is any more; more and more we're talking shades of grey.  Certainly it's nothing to get screamy about. > Have you ever setup an email client?  I think so.  Over the course of my 17 year career as a Unix hacker, I've also written about 20 sendmail.cf files, most from scratch (starting with a UUCP feed), as well as written about a million lines of Perl, including the first opcode-based safe remote execution protocol in any language anywhere.  Somewhere in there may have been a few e-mail clients on desktops. > If you did you had to setup the email server for getting your email > and choose POP3 or IMAP4 and then an SMTP server for outgoing, Well, maybe on Windows.  I distinctly remember not having to do that on Xenix, SCO Unix, Unixware, Irix, HP/UX, Domain/OS, RSTS/E, VMS, Digital Unix, Linux .96c, QNX, VxWorks, *BSD, BSDI, Netware, or PalmOS.  For that matter, I didn't have to do that on Windows, either. > or > if you leave that blank it tries to use the same server you setup > for incoming.

It happens to the best of us.  Good luck with AppsAsPeers.com; if you need any pointers, I have some work I did in 1996 which could be relevant.
