Many thanks for your help, Jason. I think I've hit a snag since the
routing server thinks the mail is local, so it won't do a callout.
The routing server thinks it is example.com. Howerver I force mail to
example.com to another internal host:
router:
accept_relay_for_example:
driver = accept
domains = example.com
transport = local_smtp_example
no_more
transport:
local_smtp_example:
driver = smtp
hosts = 192.168.181.254
hosts_override
Both servers are Exim (4.52) servers.
Thanks for any further tips.
