I realized the part of the patch that installs the README should install
it in "share/doc/msmtp", so I will make that change.

Sure. Here's a basic configuration file for msmtp itself:

---

defaults
auth on
tls on
tls_trust_file /path/to/ca-certificates.crt

account account-name
host mail.example.com
from me@example.com
user me@example.com
passwordeval the rest of this string is an invocation of my password manager

account default : account-name

---

Once you've got that in a file called ~/.msmtprc, you can do this:
echo here's a patch | msmtp guix-devel@gnu.org

Or:
echo here's a patch | msmtpq guix-devel@gnu.org

The second method will queue mail for you in ~/.msmtp.queue if
necessary, and the queue is logged in ~/.msmtp.queue.log . The mail will
be sent the next time you are able to send mail.

In my Mutt configuration, I use it like this:
set sendmail = msmtpq
set sendmail_wait = -1 # background the 'sendmail' process but watch for
		       # a return code from msmtpq.

Users can inspect and work on the queue with the 'msmtp-queue' command,
which "calls msmtpq with the --q-mgmt command ; it exposes routines for
queue management and maintenance".

Configuration of msmtpq is supposed to be done by editing the msmtpq
script itself, but in my opinion the defaults are sensible and don't
need to be changed. I didn't even realize it was configurable until you
asked for this synopsis and I've been using for it about a year.
