I'm saying that you need to investigate why crontab and mutt behave
differently.

For example, perhaps "crontab -e" does not pass TMPDIR to the spawned editor:
https://bugs.debian.org/19237

I verified by doing:
M-: (getenv "TMPDIR")
in the Emacs spawned by crontab that this is indeed the case.

So yes, I think it is a crontab issue.
