[Mailman-Users] distributing load to multiple server for announce-only list.

[bob 001]

Hello Experts,

Can someone suggest distributed server configuration of fairly large
(50k+ messages ) announce only list?

List is getting increasingly large and I am thinking if there is any
way to distribute the load to muliple linux/mailman servers.

Currently it takes almost whole day to send single message to this entire list.

Is it possible to distribute such load?  Or it should be done at
postfix level? Any suggestions?

Thanks in advance,
Bob.
