One of the websites I've written on a LAMP stack sends mail to all 7,000 
users once a month or so.

One thing I find to be very, very helpful in the process of learning 
what makes a "good" mail and what does not is to have an inbox that is 
being filtered by SpamAssassin.  That way, you can look at the message 
headers (SpamAssassin adds its own headers indicating which tests your 
message has failed) and determine what you need to fix. 

Generally speaking, my advice is to stay away from trying to mimic MS 
Outlook.  Less headers is probably better.

Sure, SpamAssassin may not follow the same rules at Hotmail or Yahoo!, 
but neither are likely to make their spam detection routines public 
anytime soon.
