How Exchange servers communicate with one another RRS feed

  • Question

  • Hello Experts,

    I have a simple question as mentioned in the title just to understand Exchange servers better.  From some articles, I learned that Exchange servers use RPC to talk to each other. Do they use random RPC ports?  And what send/receive connectors do they use when Ex servers talk to one another?

  • Hello,

    Unfortunately, your statements didn't answer my questions. I was asking the mechanism of sending/receiving emails between two Exchange servers. 

    I performed some research, Exchange uses IntraOrg connectors and still via SMTP protocal

    That's not what you asked however. Note the article I posted lists SMTP as used between servers under the section "Network ports required for mail flow"
