We have been running several 5.2.1 boxes as mailservers and have found
them to be stable at this point as follows:

running sendmail, we have 3 boxes load balanced that handle upwards of
1.5 to 2 million attempted email deliveries (I say attempted because a
lot of them get rejected by rbl lookups).

running sendmail + mimedefang + spamassassin we have 6 boxes load
balancing about 1/2 million emails. We do have an issue (which I have
posted here previously) concerning softupdates/kernel panics yet to be
resolved. I suspect that it is the mimedefang temp files causing this
and I am experimenting with moving those to a RAMdisk as a solution.

running courier-imap + procmail + qpopper and/or ipop3d on 3 boxes
without a hitch. Only tweak we had to do on the boxes with 20k+ local
accounts was create an /etc/nsswitch.conf file to have lookups done by
file rather than the [default] nis; this sped up the authentication
process immensely

All in all, I would say run with it!!
