Hi,

we already have limits set high (not copy)
number_per_ip 100
max_number 5000
sendq 100kbyte
max_local 5000
max_global 5000

in fact the problem is when _many_ users try to connect at once,
similar IPs get refused. they reconnect later fine, while still having
the others, so its some connection-protect thing
