Hi,
Could be wrong, but my reading of TFM suggests smtp_accept_max_per_host
applies even to "reserve" hosts.
If so, Randy needs to make smtp_accept_max_per_host an expansion dependent
on calling IP address.
When smtp_accept_max is set greater than zero, this option specifies a
number of SMTP connections that are reserved for connections from the
hosts that are specified in smtp_reserve_hosts. The value set in
smtp_accept_max includes this reserve pool. The specified hosts are not
restricted to this number of connections; the option specifies a minimum
number of connection slots for them, not a maximum. It is a guarantee
that this group of hosts can always get at least smtp_accept_reserve
connections. **However, the limit specified by smtp_accept_max_per_host
is still applied to each individual host**.
