We do have an old Exchange 2010(yes, i know) as our mail server. Exchange 2010 IMAP protocol only supports tls 1.0 or ssl3 as backup protocol. We have disabled ssl3, so our only option is tls 1.0.
Our problem, we have to setup an IMAP account from an application to Exchange, however, this application only supports tls 1.2 and tls 1.3 which is not option for us.
To my understanding the only possible solution is to use a proxy between the application and exchange, which accepts 1.2 or 1.3 tls connections, terminates them and pass them to exchange with tls 1.0 or unencrypted.
My first question is, is this even possible? My second question is, is it possible to setup a mail proxy only for that specific application?
I am not really sure on how to approce this (except a new mail server)
Do you have any advice? Thanks to anyone willing to point me in the right direction
