Restoring mailboxes from backup duplicates messages in POP clients

2019-04-10 Thread Luis F. V. Gomes via dovecot

Hello


I had a disk problem and had to reformat it. All mailboxes were backed 
up using rsync.
After I restored the mailboxes, the POP clients (Thunderbird) that 
were configured to leave the messages on the mailserver for, let's 
say, 30 days, didn't understand that some messages were already 
transfered and the users got duplicated messages in their Inbox.

How can we avoid this?
