[X4U] Mail.app and mac.com in cahoots?

[DZ-Jay]

Hello:
	I just installed Little Snitch (thanks to all of you who recommended 
it! I come from the Windoze world, and I didn't know of a counterpart 
to ZoneAlarm, until now).

	Anyway, whenever I open a message in Mail.app that comes from someone 
with a .Mac address (@mac.com), Little Snitch shows that Mail.app wants 
to connect to homepage.mac.com on port 80.

	Does anybody know what this is all about?  I have the "buddy" status 
thing, and images on html, disabled.  I also cannot find any special 
Header (e.g. for return-receipts), nor a Web-Bug encoded in a MIME body 
part (they're all text/plain or text/enriched), that would trigger a 
call back home.

	Like I said, I come from Windoze, so I'm paranoid by nature, and my 
first impression is that Apple wants to track views or deliveries of 
.Mac mail... (?!)

	Anybody has any details on this?

	dZ.
