Well, recompiling SASL *should've*
taken care of that, but you could also
try disabling APOP in
/etc/imapd.conf:
allowapop: 0
Restart Cyrus after you make the
change. If that helps it means that, for
whatever reason, Cyrus still uses
/dev/random instead of /dev/urandom ...
if it doesn't help, something else
must be wrong. I have no idea what that
might be.
