You don't need to use "mail" as your local agent. There should still be
some bare-bones program called lmail or Mail or rmail or maybe even mail
that will accept a message and either deliver it or give it to the MTA for
| How can I do it ?
However, if you must do it or wish to do it within a procmail recipe,
! `cat userfile`
Note that the envelope sender in the From_ line will now be you instead
of the original sender; however, the From: header will be unchanged.
If you name the file by a relative path, it should start from $MAILDIR.
If the userfile gets to be too long for LINEBUF but still fits inside your
shell's command line limit, force a shell by adding a semicolon:
! `cat userfile` ;
or if you need to make two or more files of addresses,
! `cat userfile1`
! `cat userfile2`
! `cat userfile3`
and so forth.
