Im having Exch2010 org with Edge servers for incoming and outgoing traffic. I have a bank that request TLS gateway to gateway for emails.
Will the self signed certificate do the job for TLS, and what settings shall i perform on the edge to enable such requirements?

Do not remove the self-signed certificate, however, as Exchange will continue to use that one internally for intra-organizational SMTP.

One thing to note. Opportunistic TLS is available by default, so if the bank supports it as well, you dont have to do anything to get a SMTP TLS connection. If they require a mutual, trusted - always on connection, then you need to set that up.
