Postfix has some out-of-the-box settings that make it particularly well suited 
for the role of being an MTA for a mailing list manager like Mailman.  With 
work, you can probably get a configuration for Exim that will perform nearly as 
fast for the same size of list, but Exim is designed primarily for other 
purposes than maximum performance.  As the list grows larger, the performance 
gap between a well-tuned postfix configuration and a well-tuned Exim 
configuration is likely to grow.

On the other hand, some people will find it easier to administer the Exim 
configuration than they would postfix.


If ten minutes to send out your list is actually acceptable for you, then don't 
worry that someone else can get their entire list sent out in 120 seconds, even 
if they're the same size and they're doing all the same crypto operations.  You 
need what is good enough for you, and you don't need to be comparing yourself 
to someone else.
