Re: Multihomed Sendmail question

I think something can be done.

I'm using also a multihomed system with load balancing between interfaces. It does not use a default gw, instead, uses some "round robin" method to select the output interface. You can also choose a weight for each one to give more or less preference.

Take a look at: http://lartc.org/howto/lartc.rpdb.multiple-links.html

I'm using RHEL3 with sendmail-8.12.11-3.3.

The system is multihomed - sendmail accepts mail for multiple DNS domains, and is bound to listen to multiple IP addresses.

I have some locally-running processes which occasionally send outbound mail via sendmail.

When sendmail delivers these messages to the outside world, I'd like it to use the same IP address for creating the outbound socket, as the one which accepted the email for delivery in the first place. But I can't figure out how, and instead, sendmail is always using the primary IP address of the machine for outbound mail.

Can this be done?

Thank you,
Bryan
