Just do a tag-pattern (bound to T here), put in ~= as the pattern, then all duplicates will be tagged. After that, you can delete tagged messages (bound to ;d, or just d if you have $auto_tag=yes).

Not tested (yet)!

1. stop zimbra
1a. check if every process is really stopped. don’t want to see stalled mysql or something – happened to me once
2. tar zimbra installation folder
3. tar /var/lib/rpm !!! (I forget often to do this)
4. START ZIMBRA!!! (else upgrade could fail)
5. upgrade
6. if everything works, delete backups, else untar and try again

Alternatively, if you want to accept all BCCs to the list and get rid of this message entirely, go to Privacy Options / Recipient Filters and set the require_explicit_destination option to be “No”. This should be the first option on the page, and by default, Mailman will set this option to be “Yes”.
