RE: Throttling mail
Postfix's anvil feature may meet the need. Its available in the CVS snapshots. Some basic documentation is at http://www.porcupine.org/postfix-mirror/newdoc/anvil.8.html -----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com]On Behalf Of Sam Hayes Merritt, III Sent: Thursday, March 25, 2004 7:58 AM To: firstname.lastname@example.org Cc: email@example.com Subject: Re: Throttling mail On Thu, 25 Mar 2004, Adi Linden wrote: > Does anyone have any resources on building a mail relay that would limit > the amount of email a single user or ip address can relay over a given > time period? http://monkey.org/~jose/software/vthrottle/ It allows you to say you will only take 1 email from an IP in a given period of time, and you can whitelist and more. What I'm looking for that would be even better is vthrottle added onto, or something else that I just haven't found yet, that would have a sliding window X and say that within X we will only take Y emails, and block if its above that. Have X and Y be a generic setting and then the ability to change them for a given netblock, so that AOL and other large providers do not get hit by it. But as it is, libmilter vthrottle looks like the best there is right now.
