Error: Mailbox INBOX: Sync failed

Tue Nov 24 13:46:15 EET 2020

Just saw in my logfile this line appeared:

imap(xxxxxx)<56614><CMMJw9i0aoBSsH9H>: Error: Mailbox INBOX: Sync failed 
for mbox: Expunged message reappeared to mailbox (UID 174550 < 174552, 
seq=11, idx_msgs=9)

Looks like messages' UIDs are mixed up?
I thought that if Dovecot sees broken X-UID headers for "new" messages, 
they're silently fixed?

Can you tell how I can correct this error/warning? Thanks!

BR, Jos
