Re: How I "turn-on" e-mail?

Yes,

This works good; port 25 is now open on my box.

Now, I'm stumped by another obstacle.

When I send e-mail to the host,
it bounces:

PERM_FAILURE: SMTP Error (state 9): 550 5.7.1
<root@xxxxxxxxxxxxxxx<dbikle@xxxxxxxxx>>...
Relaying denied

This smells like another configuration issue in my sendmail.mc

I'm not sure what to change though.

How do I relay e-mail to my host?

Look in your /etc/mail/sendmail.mc file for something like the following:

dnl # The following causes sendmail to only listen on the IPv4 loopback
address
dnl # 127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
dnl #

The line that binds it to loopback is the DAEMON_OPTIONS line. comment it
out like this:

dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Save that change, and you should be able to run "make -C /etc/mail" and
restart sendmail. Thats it =)
