Hello,
just to use "the other MTA" as an example.
Postfix has an option : smtp_tls_security_level = may
Which tells Postfix to send email with TLS if the other server says
STARTTLS in its EHLO
i have found a Exim
workaround.

Code:
remote_smtp:
driver = smtp
hosts_require_tls = *
tls_tempfail_tryclear = false
tls_verify_certificates = /etc/pki/tls/certs
But this requires always TLS. while not all servers are yet TLS enabled.
is there a way to do this on Exim?
