[Mailman-Users] How to 'export' mailman subscriber list

This is a very important thread here.  I just sent 1200 emails and none 
of my hotmail subscribers seem to have gotten their emails and I think 
this is exactly why.

So does anyone know how to address max mails per transaction in 
Postfix?  I'm going to go and add this question on that list.

Thanks Mark
