IANAD (I am not a developer) but I don't think I this a worthwhile approach for two related reasons: * it costs us (the mail admins) too much * it costs spammers too little We would need to go through the effort of implementing this in code, then setting off resources (disk and CPU) to checksum and record these attributes of incoming messages. In response, spammers would only need to insert a %RND_MSG_ID to render all our efforts useless. - Jon -- [EMAIL PROTECTED] Administrator, tgpsolutions http://www.tgpsolutions.com
