Should be fixed in the attached patch.

This too.

I thought the patch I pulled in from Debian made it into a shared library.
It brought it from a .a that pymilter would not build against to a .so that
it would build against. This is the first time I build C libraries for
distribution so I have no idea what I'm doing.

I seem to have misplaced my package definition for pymilter when I rebased
on master so I have to confirm again that this libmilter is actually
usable. There was something about the pymilter tests not running IIRC.

I think something somewhere in the build system wants to add a number after
that dot, but that there was no number available so it just added an empty
string after the dot.

I think I just took it from Debian for some reason:
https://packages.debian.org/experimental/libmilter1.0.1

Hard no on that.

Yeah, that is what I intended. I intended to only change the metadata
attached to the libmilter package in the Guix package repository.

Added a description and removed the period from the synopsis.

I will keep the website as sendmail.org despite the redirect, the patch
will not start with the filename for libmilter. I do not know what to do
about there being no "updater" for sendmail, but then again the last
release was in 2016.
