There are discussions of this in the list archives. An old post at
says the magic number for AOL at that time appeared to be about 17.
However, see articles 4.11 and 4.12 in the FAQ
(http://www.python.org/cgi-bin/faqw-mm.py) which say the optimal value
for SMTP_MAX_RCPTS is in the range 2 - 5 from a performance standpoint.
