I might add that the Interceptor front end (Alligate) does have some capabilities in this area. I am not really familiar with Hijack myself, but Alligate tracks volume from every senders IP address regardless of whether the message is incoming or outgoing. You can, for example, limit messages from a particular client (or a user definable subnet range of that client) to 'x' number of messages in 'x' minutes. You can also limit the number of concurrent client connections to deal with multi-threaded spam blaster apps. These features are designed primarily for incoming mail, however they work equally well throttling outgoing email.
In order for a message to be counted as one "hit", it must be a separate connection. Messages with multiple CCs are only counted as a single hit. So you can basically set it to reject connections with a 550 error if they send more than 25 messages in 5 minutes, or whatever suits your needs. The client will not be able to send a message again until they cease activity for 5 minutes or whatever you have set the time limit to be. Specific IP addresses or ranges can also be excluded from volume metering if you like.

Declude Hijack is not supported with Interceptor.

It has been great and the transition was very easy. Dan From: [email protected] [mailto:[email protected]] On Behalf Of David Barker Sent: Monday, May 18, 2009 1:04 PM To: [email protected] Subject: RE: [Declude.JunkMail] BackScatter Hi Todd, Alligate has way better greylisting capabilities than SmarterMail. SmarterMails implementation is somewhat dangerous. You need to be able to accurately qualify which messages should be greylisted. Alligate is the only greylisting implementation that does this. I don't believe you would have this problem if you were running Interceptor or the Alligate/Declude combination, and I am sure other Alligate/Declude users would agree with me. If you are interested, I can work with you to give you an upgrade path to Declude Interceptor from your current license.
