Mass mailing of our users

[Steve Lushing]

I have a question about sending mail out to the internet. We have a shell 
program that mails out a newsletter to approx. a 1,000 users on the 
internet. The problem is that when this program starts, it takes up a 
lot of UNIX CPU time and make the system extremely slow. What we want 
to know:

	- Is there any public domain software or programs that can handle 
	  mass mailing more intelligently without clogging the system.

	- We had seen mailing from private groups and we are interested in
	  how they can do the distribution of all their user automatically.
	  
Basically we are looking for a way to mail our newsletter to our users
without clogging up the system.

Thanks in Advance.
