A thousand consecutive mails to a single recipient is a mail bomb and rather
than expecting stunning performance from MTA in helping the user get
annoyed, any admin would reach for the banning commands ASAP. The result
remotely relevant to the real world is the last one, one with 100 mails to
10 recipients. Frankly, I expected the margin to be in Postfix's favor
considerably more than 125/s vs. 91/s.

Note that that's with version 3.33. I would hope that if this was reported
as a bug to the maintainers, with Exim 4 it was fixed. On the same note,
the Postfix version is also old, so a newer test would be more useful.
