I was assuming that it was just a virtual address that mapped to a list of remote recipients. Then it would just be a case of forwarding mail with SPF getting in the way. Adding SRS would fix that without the need to migrate to proper mailing list software. That's what I meant by "less intrusive". But only if their list needs are simple and fairly static. Otherwise, migrating to proper mailing list software would be worthwhile. cheers, raf
