The choice of POP server depends on many things: mailbox format, security, speed, sometimes even MTA. The following are some POP servers with some descriptions - look around, and then find one that suits you: 1. qmail-pop3d - works only with Maildir format. You can use it with any MTA - qmail, exim and postfix do direct Maildir delivery, sendmail can be coaxed to do Maildir with maildrop as the delivery agent. This POP server is modular - the authentication is done separately with another program called qmail-popup. By default it supports only plain text passwords, but can very easily be modified for APOP. qmail-pop3d is very fast and small. 2. cucipop - works with mbox format. very fast and very small - supports /etc/passwd by default. It can be modified for other auth schemes, but personally I couldn't really follow the code very well, although I've heard is is well written, if not clearly commented. 3. UW POP+IMAP server - supports mbox, mbx and various other formats. I found it very inflexible - not much support for alternate auth schemes. Also very big. 4. Our favourite qpopper - slow, big, buggy (older versions), the list goes on. Avoid it if possible. 5. cyrus - this one is a POP+IMAP server all in one. However, it works in "sealed-box" mode. You pipe messages from your MTA to cyrus's deliver program, which goes and stores the mail in a format internal to cyru,s and the only interfaces to it are POP and IMAP. Very fast. People say good things about it. However, by default it only supports /etc/passwd, and Kerberos. I don't know about APOP. -- Anand To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
