标  题: MX records and sendmail

Hi all!

I have a big problem. Here is the scenario:

Our corporate email system is Microsoft Exchange (NT-based). However, our
internet gateway, and also SMTP Relay host, is Linux/sendmail. Our MX
record points to the Linux machine (glory.prio.no, 194.19.122.161). When
sendmail receives something it doesn't know the address of (say
[email protected]), and who IS a user in Exchange, it bounces the mail.

How can I set it up to forward all mail from unknown users to the SMTP
connector on NTSPRIO2 (ntsprio2.prio.no, 194.19.122.162), which is our
Exchange server? The Exchange SMTP program already transfers all outbound
mail through the Linux box (has it set up as an SMTP relay host), but, as
I've pointed out, doesn't want to receive mail because sendmail is
incorrectly set up.

Any help on the topic would be greatly appreciated.

In your sendmail.mc put these lines :
FEATURE(mailertable, hash /etc/mail/mailertable)
define(`LUSER_RELAY', ntsprio2.prio.no)dnl

And in mailertable
prio.no         esmtp:ntsprio2.prio.no
.prio.no        esmtp:ntsprio2.prio.no

sendmail on linux box is probably setup to accept mail for [email protected]
If the scenario is like this "there are some [email protected] who are on
linux and some [email protected] who are on linux", you can use aliases to
forward the nt users email to forward to NT smtp(I hope) server.
Otherwise, change sendmail.cf so that it doesn't call itself prio.no, only
glory.prio.no

To change sendmail.cf, find a line with the text "Cw" at the begininning,
and remove only prio.no from that line leaving "Cw" with anything else or
even blank.
