Running an MTA (Exim) on GuixSD

Running an MTA (Exim) on GuixSD

Hi,

I'm using GuixSD 0.9.0. It seems the only Mail Tranfer Agent (MTA) packaged
so far is Exim. However,  simply installing it doesn't seem to enable the
sending of email (e.g., via 'git send-email'). I'd like to run Exim as a
daemon on system start-up so that I can send email from within GuixSD. Has
anyone already made a service configuration for Exim in GuixSD? Is anyone
currently using Exim on GuixSD as an MTA at all?

If not, I'd be interested in helping to make it happen. I'm just not
familiar with running Exim or writing service configurations for GuixSD, so
some pointers on how to start would be very welcome! I can probably figure
the rest out as I go.

Thank you,
Chris Marusich

It would be great to have more services and a proper MTA!

Not to distract you from that but there is a relay-only MTA in Guix:

But a full Exim setup would be great :)

Not that I know of, but it would be good to have.

That would be great :)

Section 7.2.14 (Defining Services) in the Guix manual is the relevant
reference.

I guess the two existing services that are most similar to what would be
needed for an exim-service are 'nginx-service' in gnu/services/web.scm
and 'postgresql-service' in gnu/services/databases.scm, so I would look
there for inspiration.

Feel free to ask more questions as they arise.

     Thanks!
       Mark

Hi Mark and Andy,

Thank you for the quick response. I'll take a look at the information
you've shared. It'd be nice to be able to do my email from within
GuixSD!

Thank you,
Chris
