tls

Hi,

I need to configure Exim to require TLS when sending emails to a specific domain.

I know that I can use

 hosts_require_tls = host

in the smtp transport. But it sounds like that requires that I set the host of the receiving mail server. I would instead like to specify the domain.

Also, if I use this, will all other hosts/domains work without TLS? Just want to confirm before I implement.

Thanks.
