Hi all,

I'm running a mail server that I recently migrated to GuixSD, and I
found this issue when trying to get opensmtpd set up.

When using authentication from a table, opensmtpd would crash whenever I
tried to authenticate. I found this patch which fixes the issue. It's
already been merged into the opensmtpd master branch[1], and will be
fixed in the next release which apparently will be around
October/November this year.

I also noticed another issue which I'm not 100% sure how to solve
properly. When rebooting the server, opensmtpd fails to start. I think
the reason is that the shepherd service only has '(loopback) listed in
its requirements, and I think it might be trying to start the server
before the network comes up. When I ssh into the server and start it
manually, it works fine.

My first thought was to change the requirements to '(networking), but
could that cause issues for people who only use opensmtpd as a local
delivery server?
