I am working with the output from cron. The From: and To: headers are
like:
From: "(Cron Daemon)" <rgm>
To: rgm
Where the string rgm is from the cron env MAILTO, which is unavailable
outside of cron (typically it is set to USER).
What I want to change them to is:
From: "(Cron Daemon)" <rgm@$HOSTNAME>
To: rgm@$HOSTNAME
I tried the -R option, but I am not using it right, as it does not
seem to change anything:
formail -R $USER $USER@$HOSTNAME >> mailfile < cronout
Is this possible and how?
I think I have got it with some help:
formail -i "Date: $(date +'%a, %e %b %Y %T %z (%Z)')" -a Message-ID: -I
"From: (Cron Daemon) <$USER@$HOSTNAME>" -I "To: $USER@$HOSTNAME" -s procmail
This assumes that the cron env MAILTO==USER
Too bad there is not an env var for the full user name.
