Hello, I am running dovecot 2.2.12Current mail storage is sdbox and I am trying to compress all emails, which works fine, except for a few old mailboxes.
If I run the following dsync command "dsync -u flea -o "mail_plugins=zlib" mirror maildir:~/ndbox" It fails with:dsync(flea): Error: Exporting mailbox INBOX failed: Backend doesn't support GUIDs, sync with header hashes instead
Doing "doveadm dump flea/dbox/mailboxes/INBOX/dbox-Mails/dovecot.index" reveals that there are very old mails (about 5 years ago) without any guid like that one:
RECORD: seq=1, uid=1560, flags=0x00
- ext 1 modseq : 16043 (ab3e000000000000)
- ext 3 cache : 396 (8c010000)
- cache offset=396 size=20, prev_offset = 0
- guid:
So, my question is: is there a way to force dovecot to assign a guid to
those messages?
Best Regards
