First off, I would like to apologize if any of the information presented here comes off as obvious and an insult to anyone's intelligence / knowledge. This is not the intention by any stretch — I simply have to go on no assumptions of relevant knowledge and as such try to explain, at least briefly, most concepts involved.

So, how does sending mail between servers actually work? The sending server (acting as a Mail Transfer Agent, or MTA) connects to another MTA using SMTP (Simple Mail Transfer Protocol). The negotiation starts by a EHLO command where the sender tells the receiver its identity, and then tells what "From" address it's sending for.

In case of your server, it says:

"Hello, I'm server.example.net, and I'm sending mail on behalf of [email protected]"

Generally, the receiver doesn't have a confirmation (from this connection alone) to go along with this; all it sees from the connection is the IP of the sender (in your case, 11.22.33.44).
