TLS settings: ingoing, forwarding, outgoing

I have some problems understanding the TLS settings, because there should be several settings:

1) Incoming Mail
a) Policy for accepting TLS: e.g. only encrypted or also unencrypted
b) TLS-certificate (where to configure a real certificate which matches the external hostname)

2) forwaring of incoming mail to other (internal) servers
This seems to the only thing to be configurable in the TLS-Tab per internal domain.

3) outgoging
a) If the mail gateway is used as a smart host for outgoing mail, as recommended, how it can be configured to send out mails only encrypted?
b) When the mail gateway has to send out all mails via internet provider smarthost: Where to configure the user name and password?
