Basically, if I setup one of these boxes as a > mailserver, and it will only ever be a mailserver, can I expect the 5.2.1 > codebase to behave in the long term? > 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!!
