How do I configure exim4 to route all emails via a third-party SMTP server when
the sender's domain, recipient's domain, and server hostname all match?
I followed this
great answer and have exim4 sending emails to addresses at other domains tested and working from an Ubuntu server. My only issue is that emails where both
the sender and recipient share
the same domain as
the server hostname, they never leave
the server (and this is
the expected behavior).
For example, sending from
[email protected] --
[email protected] works fine, but sending from
[email protected] --
[email protected] just routes
the mail locally to /var/mail/account2, without passing through
the third-party SMTP server.
I'm using Google Apps at my own domain and want to send emails from
[email protected] to
[email protected] from a machine with
the hostname example.com.
I want to route them through Google's SMTP server so I see them in my other email clients. Is this possible?
Very similar questions (but for postfix) here and here.
