Ah. Well, if imapd wants the cert to be for the router, remake it for
the router. Check the OpenSSL docs. It's not as complicated as it
will seem at first. Cyrus doesn't really care what the cert is for,
but I guess if UW does, you might want to check the configs to make
sure the hostname doesn't need reconfiguring.

Yes and no. POP is fine if you only ever check mail from one system.
Otherwise, imap is more appropriate. Security is a separate issue
altogether when you look at it this way.
