Creating a global procmailrc file that forwards to an Exchange server

  • 772

I need to forward all messages received on one server to another server (Exchange box). I know how to forward for an individual, but I am unable to forward for all addresses to their respective destination. The usernames are all the same, as is the domain name.

I've seen tons of documentation online for user-based procmail files, but global procmailrc documentation is scarce.

Again, this is for a GLOBAL procmailrc file that will affect all users. None of the recipients have home directories on the Linux box for which I would create individual procmail files (which is also an administrative nightmare).

EDIT:

To sum up - how do I create a global procmailrc that forwards mail for all users?

  1. Oh now I see. That's an easy one. Reading the manual of procmail it states:

       If  no rcfiles and no -p have been specified on the command line, proc-
   mail will, prior to reading $HOME/.procmailrc, interpret commands  from
   /etc/procmailrc  (if  present).   Care  must  be  taken  when  creating
   /etc/procmailrc, because, if circumstances permit, it will be  executed
   with  root  privileges  (contrary  to  the  $HOME/.procmailrc  file  of
   course).

    And in that /etc/procmailrc you forward mails as in every procmailrc:

    :0
[email protected]

  2. Do you need the messages delivered on the Linux host in the first place? If not, you could set up your MTA so it would simply forward all mail to the Exchange box without trying to deliver it locally, hence without any need for local forwarding via procmail.
