Re: [Nolug] Cox's idea about fighting spam

The only thing I have to add to this is, is that TLS works nicely in

strengthens security, especially if your smtp authentication is using
your 'system' password file
or directory service. 'Most' imap/pop mail programs will support ssl on
port 25 including pine.
