Thanks for the tip. Is there a program available to do this presorting or
should I look to script my own?
How much faster is presorting it by domain? (It currently takes about 12
hours to prepare to send to 200k recipients)

I'd recommend presorting your list by domain and then delivering 15
addresses
per message at a time. This is what we do for my company's weekly
newsletter with 275k subscribers. Note that 15 is about as many addresses
per
envelope that you'll get before some sites will refuse the mail outright.
Also
note that even if you do this, you'll probably hit rate throtlers at AOL,
Compuserve, and others which will automatically junk your mail with no
notice
to anyone.
