You can install 'emacs-guix' and activate 'guix-devel-mode', then
indentation should work properly.

'install-file' from (guix build utils) will create the directory if it
does not exist, so the mkdir-p is redundant. In addition, 'install-file'
(or actually 'copy-file') has an unspecified return value, so we end
such phases with an explicit '#t'.

Please use the (lambda* (#:key outputs ...)) form here, instead of
looking up %outputs directly.

This phase should also end on a #t for the same reason as above.

I would shorten synopsis to something like "Featureful SMTP test tool",
since the other details are mentioned in the description.

Otherwise this LGTM, sorry for the nit-picks! Can you send an updated
patch? :)
