After my difficulties a few weeks ago with the existing greylisting plugin, I spent a weekend writing one of my own and now have it in production on my firewalls.
Advantages that this plugin has over the one that comes with qpsmtpd include:
* It does not require or use file locking.
* It stores the data in the file system for quick access and modification
using command line tools.
* It has hooks allowing source addresses that match a pattern to be
folded togther into the same buckets to minimize delays when VERP
is used.
* It can pool all hosts in a subnet together for sites that may send a
message from more than one address on a network.
More information and a link to the software may be found on my blog at:
