Hub Transport server. Which one accepts inbound messages on TCP port 25?
A.
SMTP connector servername
B.
Default servername
C.
Client servername
D.
Receive connector servername
Explanation:
The Default servername SMTP receive connector accepts mail on TCP port 25, which is the default
port for receiving messages from SMTP clients. The connector accepts mail on all installed network
adapters in the Hub Transport server by default, and it also accepts the inbound messages from all IP
addresses on the network by default, but only from Exchange servers. Additionally, this connector
will not accept anonymous submissions.
