I think from a practical standpoint there's little difference between
5 and 10. The chances of a slow user delaying users goes down, as
does the number of users they affect -- but even if they're the first
delivery attempt, the delay is still fairly minor, and you're adding
to the MTA load in number of queues to deal with, which can cause
tghrashing in your mail queues. It also decreases the ability to
leverage a connection to the remote site, adding to your network
volume IF you have lots of users to the same site (like AOL). If
they're spread around a lot, that doesn't matter.
So the asnwer is "it depends". The optimal number is 1, but maximizes
the imapct on the MTA, and unless you're customizing email per-user
or VERPing, 1 is overkill.
