Hello,
We are running Dovecot 2.3.18 (together with Postfix) on CentOS 7. It uses a Maildir structure.
We have a user who has organized his mailbox as shows up at the end of this mail. The user had forgotten that he had renamed his "Grants Active \ European" (.Grants Active.European) folder to "Grants Active \ International" (.Grants Active.International), he thought that it was lost and requested a restore of "Grants Active \ European" (with all of its subfolders) from backup.
Since we did that (using a simple "cp -rp" from a backup, observing timestamps, ownership and permissions), mail client software won't see "European" mail folder in"Grants Active" mail folder; "International" mail folder shows up but only with two folders, those which do not exist in "European" branch (obviously, these were created later).
I have tried to run the command "doveadm index -u userx Grants\ Active" and likewise for each and every mail subfolder under "Grants\ Active"; I have also tried deleting the dovecot.index.cache and dovecot.index.log from the latter ("Grants\ Active") and then run:
doveadm -vD force-resync -u userx Grants\ Active but it didn't do the trick: Mail clients are still stuck as I explained.
In the end, I thought that the snag might be that mail folders that are not appearing have identical (duplicate) UIDs; As an example:
[root@mailx .Grants Active.European]# cat dovecot-uidlist 3 V1548680759 N1 G64e70a1130343f61003c0000715faa8d [root@mailx .Grants Active.European]# cd .. [root@mailx Maildir]# cd .Grants\ Active.International [root@mailx .Grants Active.International]# cat dovecot-uidlist 3 V1548680759 N1 G64e70a1130343f61003c0000715faa8d
If so, how should we overcome this issue?
I guess I could simply delete the restored folders to return to an acceptable state? If nevertheless we need to restore the ".European" mail folder from a backup (as it was before getting renamed), what would be the right way to do so?
Is there another way to resolve the issue without deleting the restored mail folders?
Here is the list of mail folders in this mailbox (I have intentionally removed lots of them, to reduce irrelevant content; this mailbox includes a large number of mail folders):
Can you enable mail_debug=yes, restart, ask the user to access the folder(s) and provide those logs?
