So you have two physical servers, the old and the new one?

On the new one, i would install the latest version of FreeBSD and have it 
on -STABLE branch.

Then install relevant packages or compile up ports so that you have 
sendmail and named running

Then copy over the relevant config files for sendmail and named, so like
/etc/sendmail.*
/etc/mail/*
/etc/aliases*
for sendmail, and

/etc/named.*
/etc/namedb/*
or /usr/local/etc/named*
or /var/domain/*
or /var/named/*
depending on where you have installed named, and where the zone files are.
Default install is /etc/named.conf and /etc/namedb  for zone files.

There will probably be a few minor hiccups on the new system, but if you 
read /var/log/messages the errors should be fairly simple to work out.

Cheers
rob.
