Hello

I have a mail server that we call Discovery 192.168.1.30.
Our MX record point to mail.montrealinfo.com 192.168.1.30.
We don't have an MX record for conciergeinfo.com and conservus.ca even though we own these domains.

Then we have a faxserver that we call FAXSERVER 192.168.1.40
That server is used exclusively to send our weekly publication by FAX throught hylafax and by EMAIL through SENDMAIL.  The email is sent with the address infolettre@conservus.ca  (not @montrealinfo.com which is our primary email).

*** All info about SENDMAIL configuration on both server are at the end ***

  The problem is that the FAXSERVER doesn't seem to know "conservus.ca" at all.  I noticed that because, each week, there are many bouncing emails coming back to the FAXSERVER for the email infolettre@conservus.ca, but the server doesn't know what to do with @conservus.ca emails, so i received a Postmaster notify: see transcript for details from postmaster@faxserver.montrealinfo.com saying this :

faxserver.montrealinfo.com doesn't know _WHERE_ to relay mail to domain conservus.ca (I suppose it uses address 66.38.180.26).

You may either point conservus.ca to Discovery in /etc/hosts on faxserver:
/etc/hosts:
192.168.1.30 conservus.ca

OR
to change mailertable rules on faxserver like this
probably it's a 'mailertable' file:

conserver.ca                 smtp:192.168.1.30
