I have several Groupwise (8.0.2) postoffices and am starting to get a couple of users (each on a different PO) getting multiples of e-mails they receive. So instead of getting the one copy of the e-mail they get up to 10 copies of the same e-mail.

They may be running with an older client, so just updating them now, but what else could be causing this? and how could I fix this?
