How to set a different listener on port 465 for SMTPS?

The idea is being able to manage both plain and secure SMTP while reconfiguring all clients for SMTPS.

How would you go about this?

I have
- created new Ip interface + listener
- created SMTP authentication profile
- created a new policy that requires TLS / SMTP Authentication

I am unable to send mail and I don't receive clear messages as to why it isn't working.

Have you enabled the smtpauth profile on the new listener?

I did - but it isn't working.
Accounts are on a LDAP server - routing and accepting LDAP queries work regularly but authentications don't.

AFAIK, ironport only support TLS (which is port 587) and if you try to enable 465 just to accomodate SSL (for those that using old broken MUA) it won't work.

Ahhhh! Thanks a lot - that's why I wasn't able to find examples of such a configuration in the documentation!
