[ale] Doing without Sendmail

[Glenn C. Lasher Jr.]

When getting DSL, you're probably going to want to use ipchains to keep
your system secure anyway.  Why not put in the following entries:

ipchains -A input -p smtp -s 127.0.0.0/8 -j ACCEPT
ipchains -A input -p smtp -s your_host_name -j ACCEPT
ipchains -A input -p smpt -j DENY

...then just let sendmail run.  You should then even be able to use
sendmail to send outgoing if you felt so inclined.  I intend to use this
approach (I am also in the DSL queue) so that I can continue to have my
email arrive locally (using fetchmail) and eventually I would like to host
my email here, as soon as I get the details worked out on a good sendmail
configuration.
