we are using a smarthost in Excange2010 to send e-mails to the internet. In exchange we have a rule that all mails (*) will be send with that send-connector.
Does Exchange per default use TLS for sending mails outside if the receiving server offers TLS?
What encryption can Exchange use to send (128Bit, 256Bit). In outgoing mail I see that exchange is sending with 128 Bit. Is it possible to set it to 256 Bit?
Another question is, how it would be possible to force exchange or the smarthost to send mails to *@test.com always via a specified mx-server?
Many thanks in advance!
