[COLUG] sendmail question?

[frank_rieder at bankone.com]

If it would blindly send root mail, would it go to root at capital.edu?
That could cause some confusion for whomever the mail is received.

If you want to send all email to another server, called a "Smart Host'
(i.e.
your Exchange server) use the Null Client feature in a new m4 configuration
file, called "nullclient.mc" or whatever you choose.  Place this file in
the
directory where your "m4" files are, sometimes "/usr/lib/sendmail-cf" or
equivalent.  You'll know the right directory when you see these
subdirectories:

cf
domain
feature
hack
m4
mailer
ostype

Create the "nullclient.mc" file in this directory and add these lines:

include(`./m4/cf.m4')dnl
FEATURE(`nullclient',`<nameofinternalmailserver>')dnl
FEATURE(`nocanonify')dnl

Substitute "<nameofinternalmailserver>" with the hostname or IP address of
the Exchange Server.  Also, be cautious of the backticks vs single quote
characters above, it makes a big difference.

Save it and run:

# m4 nullclient.mc > sendmail.cf

Copy the sendmail.cf over the current sendmail.cf (should be in /etc/mail)
and restart sendmail.

That's a basic configuration, but it's a place to start.  Be aware that
this
will blindly forward all email, even if sent to "root" or another local
account.  This may not be what you want.  If it's not, then there are other
slightly more complicated ways to do it.
