I have client that we currently provide hosted exchange mailboxes via the messagestream service.
My client has frequent contact with financial organisations such as banks & brokers and today we received a request from one of the banks as they would like to setup a scan and email service using TLS (Transport Layer Security) which enables secure email traffic between servers / domains, ensuring that documents cannot be intercepted in transit.
To set up an agreement with TLS the bank needs to capture certain details from messagestream (IP’ address, Servers, certificate provider and details, etc), and similar information would be provided from the bank.
I have spoken with messagestream support who advised all Email on their Platform is automatically sent as TLS as standard on first pass; if the recipient rejects the TLS they downgrade to SSL and retry the delivery. The issue i have is that messagestream have advised that no additional configuration of rules would be supported from their side however they have provided IP addresses of their mail servers as well as certificate names.
Because TLS is already setup on messagestream servers is it possible for the secure transit of email traffic to work without the configuration details to be supplied by the bank.
I am just after some extra info if possible and wanted to know if anybody else has ever run into this issue when using hosting providers.
