I assume you still want the jobs to be run by root though, otherwise
you could just use the 'ian' account's crontab file.

Sure.  'root' always used to be special cased so that emails from
there don't go through address rewriting.  But since sendmail-8.10
that's no longer the case.  Just use the normal genericstable
mechanisms to rewrite the sender address. Read through the bits of
/usr/share/sendmail/cf/README that deal with genericstable first, but
essentially what you need is:

i) Make sure your /etc/mail/`hostname`.mc file contains:

FEATURE(genericstable, `hash -o /etc/mail/genericstable')dnl

   if not, add it to the .mc file and rebuild sendmail.cf and
   restart sendmail in the usual way:

# cd /etc/mail
# vi `hostname`.mc
# make all install restart-mta

   ii) Edit the /etc/mail/genericstable file to set up the e-mail
   address mappings you need.  That will be, minimally:

rootian

   and then process that into the .db hash format sendmail will
   read:

# make

  iii) That's all you need to do.  Send some e-mails as root to test.

Nb. this rewrites all e-mail from [EMAIL PROTECTED], not just the stuff
emitted by cron. If you want to do that, it's going to be much harder
to achieve.

Cron Mailing

[Ian Barnes]

Hi,

I am trying to find out if something is possible. On our servers we would
like all mail from cron not to come from [EMAIL PROTECTED] but rather from say
[EMAIL PROTECTED]

Is this possible? Am i making sense :P ??

Thanks

Ian
