Setting relay for internal email
in [Sendmail]
|
From: Charles on 5 Aug 2010 17:04 How can I explicitly set the mail server that I want smtp mail to go to using sendmail? In this case I want to send notifications to users from a web server (PHP). The server never needs to send outside of my company's private WAN. The server is an Ubuntu 10.04 LAMP server. We want email to go straight to our Domino server which will recognize the smtp address and deliver it. Instead it is going out to the Internet and coming back in through our firewall. I have tried 1. adding our-domain.com ESMTP:[nn.nnn.nn] to the mailertable 2. running makemap hash /etc/mail/mailertable.db < /etc/mail/ mailertable 3. adding our-domain.com to the /etc/mail/relay-domains file restarted sendmail. No change. I've done the same thing on a RedHat server and it works fine.

It may work for your purpose, too. In the .mc file for that sendmail, add something rather like define(`MAIL_HUB', `relay:[your_mailhub_IP_address]')dnl define(`SMART_HOST', `relay:[your_mailhub_IP_address]')dnl define(`LOCAL_RELAY', `relay:[your_mailhub_IP_address]')dnl or define(`MAIL_HUB', `relay:your.mail.hub')dnl define(`SMART_HOST', `relay:your.mail.hub')dnl define(`LOCAL_RELAY', `relay:your.mail.hub')dnl The "[]" around the IP address disable MX lookups for that address, which may be useful. -- Mike Andrews, W5EGO mikea(a)mikea.ath.cx Tired old sysadmin

I added the lines to the .mc file and regened the .cf with m4. Went OK with no errors. Then I restarted sendmail with /etc/init.d/sendmail restart

When I search the sendmail.cf for the IP address of the Domino server it is not there. Unless I am misunderstanding how this works, the change did not take effect. Are there any error logs for the m4 command?
