Now, did you want that in terms of "number of copies installed" or
"amount of mail handled"?   There's probably zillions of little Fedora and
Ubuntu boxes running whatever MTA came off the disk that are handling 1 or 2
pieces of mail a day, and then there's whatever backends are used by
MSN/Hotmail, Yahoo, AOL, etc.  "This MTA packed by weight, not by volume.
Some settling of contents may have occurred during shipping and spamming."

(Seriously - if 95% of the mail out there is spam, then the top 4-5 MTAs are
probably the ratware that's sending out the spam.  Something to consider...)
