Are you talking about performance loading into the MTA? Or delivery?

I'll bet one thing in the Something Else category is disk I/O. That's 
what usually nukes MTA's first (and foremost).

I really, really need to sit down and beat postfix into a pulp. But 
I've got four sites to ship before I can (two of them based on 
mailman). I'm typing as fast as I can... but I really want to get a 
handle on postfix....

Very fair. It's nice the hooks are there, and IMHO, figuring out how 
to use it properly, tune is and all of that stuff sounds like a 
perfect reason for a 2.1 release. I sure wouldn't hold up other parts 
of 2.0 for this...

I think this is a great start, and I agree -- there's enough going on 
with 2.0 that we don't want to wait for this to release it. It'll 
give us time to sit down and research the beast in different 
environments more, too.
