UPDATE: We believe this problem has been fully resolved (the fix actually was pushed on the afternoon of the 27th). But if you’re continuing to see duplicate messages, please do still contact Customer Care with the information described below.
We are aware of the duplicate message bug that is affecting some groups and are investigating the problem.
If your group is experiencing this issue, please contact Customer Care and supply the following information:
- Whether the messages are appearing multiple times in the archive or only in email.
- Whether you are the only person experiencing the issue or whether most people in the group are getting the duplicates
- Whether it is happening to all messages sent to the group or just specific ones (either way, provide the message numbers in the archive of the duplicating messages).
- Provide the full headers of 2 (or more) copies of the duplicate messages.
The headers, in particular, are vital for us to be able to effectively troubleshoot. This site http://www.fraudaid.com/find_headers.htm#service provides useful information on how to get headers for many different email clients.
