I concur.

This is not odd at all and is actually the goal of people like MSN.com. To their 
mail server, your mail server could be an MTA, MSA or MUA. They don't care... 
they'll take anything. Users cannot email WITHOUT relaying through their servers.

Now for business accounts, that's another story.
