I was in the process of setting up new server, it already had a few test mailboxes on it. why do you mention this specific version 2.3.21? el9 still is at 2.3.16. So if I add the LAYOUT:index to mail_location for my mdbox setup, it only renames Drafts,INBOX,Junk etc to some uuid (I guess)? ├── mdbox │ ├── dbox-alt-root │ ├── mailboxes │ │ ├── Drafts │ │ │ └── dbox-Mails │ │ ├── INBOX │ │ │ ├── dbox-Mails │ │ │ └── test │ │ │ └── dbox-Mails │ │ ├── Junk │ │ │ └── dbox-Mails │ │ ├── NotSpam │ │ │ └── dbox-Mails │ │ ├── Sent │ │ │ └── dbox-Mails │ │ └── Trash │ │ └── dbox-Mails │ └── storage │ ├── m.1 │ ├── m.2 │ ├── m.3 │ ├── m.4 │ ├── m.5 │ └── m.6 This server is offline any way. What would be the easiest way to do this migration? Something I can do directly on this server? _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
