	Which won't work with the majority of MTAs.  Most limit the 
maximum number of recipients per message to be something like 100 or 
200.  If the local MTA has been modified to have a higher limit than 
normal, it should deal with the issue of envelope splitting if the 
remote MTA has a smaller limit.

	The flip side of having so many recipients per message is that 
many mail systems will flag your messages as being spam, especially 
larger sites like AOL.
