Here’s my contribution: a Guile module using Mailutils to compose and
send messages:

  https://wiki.gnu.tools/git/gnu-tools-wiki/tree/code/modules/email.scm

The only thing that’s missing is a proper setup for outgoing mail from
guix.gnu.org, presumably with OpenSMTPD.  The config is here:

  https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/berlin.scm

If someone would like to help, please send a patch!  :-)  We can also
adjust the MX record for guix.gnu.org at our will:

  https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/modules/sysadmin/dns.scm


Caveat: my experience with Hydra is that you immediately receive too
much mail.  Initially Hydra would send one message per failed build,
which was then changed to one message at each status change (from
“success” to “failure” and vice versa), but that was still too much.  I
think eventually it was change to email only the committers of the
offending commits, which is probably the best option.

Thanks,
Ludo’.
