--- Comment #3 from Darren Tucker <[email protected]> ---
In 8.5 we added PerSourceMaxStartups and PerSourceNetBlockSize which
allow limiting startups by source address, optionally grouping nearby
addresses into blocks:

     PerSourceMaxStartups
             Specifies the number of unauthenticated connections
allowed from
             a given source address, or "none" if there is no limit. 
This
             limit is applied in addition to MaxStartups, whichever is
lower.
             The default is none.

     PerSourceNetBlockSize
             Specifies the number of bits of source address that are
grouped
             together for the purposes of applying PerSourceMaxStartups
             limits.  Values for IPv4 and optionally IPv6 may be
specified,
             separated by a colon.  The default is 32:128, which means
each
             address is considered individually.

If you set PerSourceMaxStartups to something lower that MaxStartups it
will prevent any single address (or block of address if you set
PerSourceNetBlockSize) from tying up all of the startups.
