We've done exactly this since around 2003. No problems reported. Before then, we used a conservative but simplistic policy where if any recipient opted to receive spam then recipients all would get the message. There were quite a few reports of stuff slipping thru, which is why we went for the defer policy as described above. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
