...except for some FreeBSD-specific info :)

Here are some tips:

1) FreeBSD uses a "MTA wrapper" which makes your mailer *look* like
sendmail, regardless of what your mailer actually is.  This wrapper is
located at /etc/mail/mailer.conf.  Mine looks like:

sendmail        /var/qmail/bin/sendmail
send-mail       /var/qmail/bin/sendmail
mailq           /var/qmail/bin/qmail-qread
newaliases      /var/qmail/bin/newaliases

This makes setting up non-sendmail mailers quite a bit easier.  IIRC the
PORT_NOTES file in the qmail port has more information about this.

2) Use sendmail_enable="NONE" in your rc.conf file to completely disable
sendmail, once you have qmail up and running.

3) Don't worry about ucspi-tcp and daemontools to start out with - qmail
will work with inetd, it will just run nicer with ucspi-tcp and
daemontools.  So you can migrate to those tools after you become
comfortable with qmail - you don't have to do it all at once.

HTH, and good luck.
