[Mailman-Users] Switch from Major Domo

[Darren Hood]

Hello.
 
I have no knowledge of Mailman and since Plesk is talking about
including it in one of their upcoming releases, I'm trying to learn
about Mailman to see how easily I can make the transition from Major
Domo (as a user), which I've been using for the past 5-6 years.  
 
Two questions on my mind for now are as follows:

1.	Is there a way to restrict who can send messages via the list?

2.	Can messages be sent in HTML format?

3.	People have tried to hack our Major Domo list.  How secure is
Mailman from a hacking perspective?  

Thanks.
