I did not save all my testdata unfortunately, but at one time, I had 2
FreeBSD P6 boxes, NFS mounting a Netapp F540, using Maildir for delivery,
and several boxes generating the email in front. The P6's were
loadbalanced with a Cisco LocalDirector.
I certainly recall it handling something like 450k+ deliveries of a mix of
5k and 100k messages, in 24 hours easily, and the netapp was not dedicated
to it, it was serving FTP, web pages, and all that stuff via other boxes.
One time the queue backed up to several thousand messages, for reasons I
never divined, but it cleaned itself up eventually, and then stayed pretty
steady.
I didn't do any significant tuning.
I have no doubts a million messages a day would be not impossible at all.
A million messages in 24 hours is what, appx 12/second, so that's
humming right along.
