While you don't provide the details in this area, I'd suspect that
your richest vein for handling this would likely be at the MTA.

Note: Depending on the size of your membership lists, the system you
discuss is more than adequate for handling the better part of a
million messages a day without undue strain.  Mailing lists are not
terribly resource intensive, not at the CPU level.  What they
consume are IO (disk and network) and RAM -- both of which appear
reasonable (tho you don't comment on your connectivity).
