It might be useful if you have a pool of servers sharing a single
database of pop-before-smtp, but I would think for that application NFS
would be adequate.
I have a greylist application with a little perl server that answers
UDP requests from qmail-smtpd. The greylist database is in a perl
table, dumped out to a file every 10 minutes in case of crashes. In
retrospect I could have done the whole greylist thing in the
filesystem, but I think the UDP request code is smaller and simpler
than putting the greylister into qmail-smptd, and the perl program
runs as an unprivileged user.
R's,
John
