Hmmm -- "qmail is too fast; how do I slow it down?" Switch to sendmail? :)
There's various ways of doing this. If this inbound mail gets passed on to
another (internal) mail server, you could make these user accounts virtual by
putting them in virtualdomains:
user1@thisdomain:alias-delay
user2@thisdomain:alias-delay
...
Then, have ~alias/.qmail-delay-default, which files all mail in a Maildir.
Then have serialmail run out of cron every hour (or every four hours, or
whatever) to deliver the contents of this Maildir onto the next hop.
