# apt-get install postfix The following packages have unmet dependencies: postfix: Depends: libsasl2 (>= 2.1.19) but it is not going to be installed I wonder what's going on? Isn't 2.1.22.dfsg1-8 supposed to be >= 2.1.19 ?
The problem here is that libsasl2-2 has "Conflicts: postfix (<< 2.3.4-3)". Unfortunately postfix does not build without extra patch, so while in plain debian unstable is postfix 2.3.6-1, kfreebsd have only package based on older version - 2.2.8-9+kbsd. You can try to build postfix from source with patch (based on) http://glibc-bsd.alioth.debian.org/patches/debian-only/postfix.diff or extracted from http://ftp.gnuab.org/debian/pool-kfreebsd-i386/main/p/postfix/postfix_2.2.8-9+kbsd.diff.gz Hope it helps.
