Sure, I'd like to try. I have only packaged for Guix so far, and have
not worked on any build systems or other code. But, I guess this is a
good time to start.

I finally figured out the problem. It turns out that my outgoing SMTP
relay (the mailjet smarthost service) is adding a
"Content-Transfer-Encoding: quoted-printable" header to my content
headers and is thus corrupting my email signature. I have to figure out
some way to work around this.

email is such a pain. I have to use smarthosts because my self-hosted
mail server is on a dynamic IP address. (Most?) mail servers accept mail
only from static IP addresses with reverse DNS records. Are there any
good free (as in gratis) smarthost services that you can recommend?
Which smarthost, if any, do you use?
