Sigh!  And what this has to do with Alpha?

It is configured into some default client-only configuration and that is
likely your problem.  Tightening up security is inconvenient.

Look into /etc/mail/sendmail.mc.  You will likely find there
something like that:

dnl This changes sendmail to only listen on the loopback device 127.0.0.1
dnl and not on any other network devices. Comment this out if you want
dnl to accept email over the network.
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

Edit this file (or even better a copy) to your liking, follow
instructions given in its header to write new sendmail.cf and restart
your sendmail service.  You need installed 'm4' and 'sendmail-cf'
packages for this to work.  A file /usr/share/sendmail-cf/README
gives quite a bit of information to a meaning of various used and
unused options in your '.mc' file.

Most likely NOT the thing to do.
