He's right.
When I was on a cable modem, I had to relay through my ISP's relay server.
If I sent mail to:
It sent 3 messages to the relay server.
The mistake he's probably making is that, with a direct connection to the
end recipients' server, is that, normally, his server would make a single
connection to that end server, and send all three recipients at the same
time.
I'd imagine that the same thing happens, while going through the relay
server, though it's still sending multiple recipients, and, therefore,
messages, it's probably only making one connection to the relay server for
each set of recipients.
So that for all @yahoo.com addresses, it's making a single connection.
For all hotmail.com addresses, a second connection, etc.
At least, that's been my experience.
