[Mailman-Users] MS Exchange as a relay computer?

This is not true for postfix. 

> Exchange 2000 has no problem sending the same message to multiple
> domains at the same time.  The remote deliver agent on most Unix MTAs

This is not true for postfix.

> so if you set the batching to 500 then you single thread your
> delivery and it can take forever for messages to get out.

This is not true for postfix.
