We are running domino 8.0 on a Linux Server. We are using notes 8.02 on the clients. Some emails are being sent out more than once. It is not on all emails or all users but some emails are being sent once, then a second time and occasionally a third time. Sometimes they have an attachment and sometimes they don't. There is sometimes a delay of a few minutes between messages but most often the delay is around 10 seconds. We used the message tracker and found that the original message and the repeat messages have the same unique message ID. They can be sent to internal addresses or external addresses. We are running a BES so we thought there might be a link there but not all users with the issue get email via a Blackberry. We have a clustered Domino server environment and one of the cluster members is off line right now but we don't think that is the issue. We have not yet found a common thread.
Where can we look to find more information about why the messages are being repeated.
Thanks for any help you can offer.
