[Nix-dev] Crontab and mail / ssmtp troubles

[M. P. Ashton]

I'm having trouble getting a rather simple crontab running on a new
NixOS installation.

The crontab is supposed to run a shell script in a user account. It
doesn't work. So I tried just having it run "echo test". That got me
this in the journal:

Oct 15 15:54:01 bode cron[22272]: (mpashton) CMD (echo test)
Oct 15 15:54:01 bode cron[22271]: (mpashton) MAIL (mailed 5 bytes of
output but got status 0x0001
                                  )

Sadly I can't see cron's mail output, because mail doesn't work either.
I installed ssmtp using networking.defaultMailServer.directDelivery =
true, but none of my mail programs, like mutt and mail, seem to be able
to find sendmail. For example:

   [mpashton at bode:~]$ echo "Hi there" |mail -s "Test subject"
   data at gtf.org
   Cannot open mailer: No such file or directory

I can force Mutt to see sendmail by putting this in .muttrc:

   set sendmail="sendmail";

Then it works fine and I can send mail successfully. So, obviously Mutt
is pointing to something like /usr/sbin/sendmail by default. Maybe
crontab is too? But I would have thought this would be patched already.

Crontab is below. Notice I tried adding paths -- this did not help.

Thanks to anyone who can offer advice here!
