Thank you for the reply.

Its resolving to the last alias on the eth0 device.

I ran the update-exim4.config.template and I restarted exim.

transport/30_exim4-config_remote_smtp

remote_smtp:
debug_print = "T: remote_smtp for $local_part@$domain"
driver = smtp
interface = ${lookup{$host_address}lsearch*{/etc/exim4/interface}}
helo_data = ${lookup{$host_address}lsearch*{/etc/exim4/helo_data}}

/etc/exim4/interface:
mydomain.com: eth0:1

/etc/exim4/helo_data:
mydomain.com: a.b.c.d
