The effect of differing policies is the concern. Sewer pipes increase in size to avoid clogs. The expiry of the message permits a bad actor to light a precision fuse before dropping their message into the flushing toilet. The effect of the expiry is that the pipe (allowance) granted the message reduces at it travels. When this becomes a problem, each MTA will want to ensure more than some amount of time remains prior to expiration. It will be unpleasant up stream of the clog created by the different and ever decreasing size pipes. -Doug _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
