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.
