Cron only sends email when the job's output is not empty. Silent jobs do
not try to send email. Is that plausible?

Looks to me like it does not queue:
% (echo To: c...@cskk.id.au; echo From: cs; echo Subject: msmtp
test;echo;echo 1) | msmtp --host=bogushost.example.com --from=c...@cskk.id.au
-t c...@cskk.id.au
msmtp: cannot locate host bogushost.example.com: nodename nor
servname provided, or not known
msmtp: could not send mail
Caveat: I have no msmtp config - that's a bare command line test.
There's a package called "nullmailer" which can be used as your system
MTA - it is intended for systems with a smarthost - upstream SMTP
server, exactly what you msmtp setup will be using. But it has a queue.
You could install it without changing your mutt/msmtp setup at all. If
it works for you, you could then switch to having mutt use the local
sendmail command (the default) instead of msmtp.
Looks like its config lives in /usr/local/etc/nullmailer.

Man page for nullmailer-send, which describes the config settings:

Disclaimer: I've not used it.
