Just following up to myself with a related question...

If I have a seperate update server, and the read-only server is working
fine, does any failure on the update server (doing relay and lastauth)
cause pop/imap/smtp-auth logins to fail?

I've temporarily offloaded the read-only stuff to a seperate box, but I
saw a re-occurence today of database hiccups on the update server, and
also saw a string of login failures, so I'm wondering if the problem has
followed me to the new db box or if the updates bogging down can hang the
password checking routines.
