Sounds good.

There is no practical limit. Perhaps one qmail-inject per 50,000
recipients? I certainly would go a *lot* higher than your current
40-100.
Remember, each inject creates a separate copy of the email in the
queue. At 100 recipients per inject, that's 650,000/100 = 6,500 copies
on disk. At 50,000 recipients per inject, that's 650,000/50,000 = 13
copies on disk.

Easy, just set the message-id in the header of the submitted
email. qmail-inject only adds a message-id if one is not present.
