Recursive aliases like that are always going to pose problems. The way I see it: - Mailman injects one mail per recipient on the list to the list members. Each also has ALL the people on the CC: line - Groupwise then receives to several people on the internal list and starts doing funny stuff with mail routing because you have the To: recipient as a list + CC: dupes. - Groupwise makes multiple deliveries because it cannot de-dupe the recipients in the To: line (they're not local, they're [EMAIL PROTECTED]), and will receive ONE email for EACH subscriber to the list and so 11 emails, each of which is expanded to each recipient internally, whether on the list or not. Solution: create an internal list in Groupwise containing ALL subscribers to the mailman list - don't CC all recipients but just CC that internal list. Subscribers to mailman list who are also on internal list get 2 copies, everyone else just one. Or better still, get rid of the internal list and subscribe everyone to the list who needs to be on it, and have just mailman manage it. Other option: make the internal list contain only those who are not subscribed to the mailman list, and subscribe an external address, aliased to that list, to the mailman list.
