Re: Mail Server

["Barry Michels" <bmichels@barrymichels.com>]

Well, since I'm the only user on my system, I block everything from the
outside and only allow intranet sending.  When I'm at work and want to send
mail using my home account, I open a SSH session forwarding ports 110 and
25.  Port 110 is totally blocked to the internet.
