Except ban block

The except ban block allows you to specify a user@host that will override a ban { } and KLINE/ZLINE placed on a broader host. This is useful when you want an ISP banned, but still want specific users to be able to connect.

Syntax
except ban { mask ; };

The except::mask directive specifies the user@host mask of the client who will be allowed to connect.

NOTE: If you want to exempt a host completely from all possible bans (except spamfilter), then you need both an 'except ban' and an 'except tkl' block

Example
except ban { mask *@my.exempted.host.isp.com; };
