Actually, I think you are off base here.

It's not Majordomo's responsibility - it's YOUR responsibility. Majordomo 
isn't a mail server. It's a preprocessing engine. It is your mail server 
that does not provide the appropriate level of protection to your clients 
and subscribers. In this modern age of rampant virii, hacks and trojans, 
anyone running a mail server has to treat the Internet as a HOSTILE 
environment, and configure and run the system accordingly.

I run Mimedefang and quite a few other pieces of software on all of my 
servers in addition to all the appropriate configurations for Majordomo. 
None of my lists have ever been used to send a virus, or have been 
compromised in the manner described.

The primary problem seems to be twofold:

1. Cheap hosts that provide almost no protection on the servers they sell. 
Therefore handing a ticking time bomb to the unsuspecting customer.

2. System administrators who do not truly understand what they are 
administering.

Responsible administration can provide all the protection you'll ever need 
- for free I might add, everything needed is either system configuration or 
software available under the GPL or similar license.

Just my $.02 - ymmv - insert appropriate disclaimers here - please send 
flames to /dev/null
