Got 4 existing 2013 mailbox servers and have just built 3 new mailbox ones (on newer hardware) and integrated them into the DAG. All databases have been moved off the old servers. Also, got two CAS servers.
The new mailbox and the CAS seem to have the default connectors installed. (anonymous is left unticket on the one though)
The old ones have all got an entry for EXTERNAL EMAIL connector. I'm guessing this is because we utilise a websense as a gateway server. But why are these connectors on the old mailbox servers and not the CAS servers? Shouldn't they just be on CAS?
Also, got entry for PRINTER and APPLICATIONS. I'm assuming this is for scanners to be able to scan to email, and also certain applications send email directly. BUT, this is only one ONE mailbox server and not the others. Again, shouldn't this be on CAS servers?
Bit of a mess. Person who set this up has left the company. Any advice on best practice here?
