Ah, in that case that's just because some people are literally sending a message to the list twice under its old and new addresses. They generally seem to be in portions of threads originating with Brian. I think what's happening is that people still send to [email protected] rather than [email protected] for any of various likely reasons, and then when Brian replies their mailer picks up something like the List-Post header and adds that too. I don't know whether it's possible to do much about this unless Brian can work out how to make their mailer pick just one of the two list addresses and stick to it. -- Colin Watson [[email protected]]
