Howdy,

Over the last week I've implemented rate limiting on clrghouz. I noticed recently quite a few polls coming from the same IP address every minute - some of them probably script kiddes, some of them BBSes that are on auto-pilot.

The rate limiting will impose the following limits:

* Maximum 2 concurrent connections,
* Maximum 5 connections in a 60 min period.

If your BBS is crash capable - most of you should be, then clrghouz can be set to poll you when it has mail available for your system.

If you dont want mail immediately, you can be set to poll mode "normal", which means clrghouz will poll you twice a day, if it has mail waiting for you.

If polling to your system fails 10 times in a row, your system will be put on auto-hold and no longer poll until you poll in and collect mail. That poll will reset/clear the auto-hold status. You'll also get a netmail telling you about it - which might be helpful if you recently changed hosts/ports and didnt update the hub.

For CRASH bbses, I recommend having a manual poll (if you want) no more freqently than 6 hrs to clear any backlog in case either side puts the other side on hold.

If your BBS is not crash capable, really only for CGnat systems, you can be set to hold, and poll in to collect mail. I recommend not polling any more frequently than hourly.

If you collect multiple networks from me, some of you do, then I suggest you set your BINKP session password to be the same for all networks, and present all your AKAs in the session - then you will receive all mail (for all networks) waiting for you in that session.

Happy to review the hourly limit as appropriate - I'm not wanting to hinder mail flow or slow it down - I'm trying to target the script kiddies or the BBSes that are on auto-pilot that poll every minute.

Any questions, please ask.
