Which MTAs are people using with mailman for large lists (> 5000 
I'm particularly interested in mailman 2.0b2 (or later :-) ), since 
that puts all recipients into a single SMTP transaction - the MTA sees 
one message with 5000+ recipients.

Different MTAs have different trade-offs.
Exim (and smail) routes all recipients before starting delivery - so 
this configuration could have a long startup delay before it starts 
delivering, but I don't currently have a feel for how significant this 
is especially where there is nearby cached DNS and a decent list 
Qmail effectively makes a separate envelope for each user, so 
deliveries will start very fast.

I don't know what postfix and sendmail do...
