Just a heads up, there have been numerous reports of this breaking other
services (ssh, ftp to Win2K servers, pop/IMAP) intermittently. We
experienced problems with some customers connecting to our IMAP servers
once we started doing this, we had no choice but to roll-back the change
and the problems went away. Weird. YMMV.
