Hi,

I'm currently running a small home-server with Dovecot. A long time ago

I configured it with SIS enabled. I would like to stop using SIS.

If I remove sis from mail_attachment_fs will the old mails that are

stored in SIS-storage still be accessible?

How can I convert all mailboxes to stop using SIS and store attachments

back in the mails?

Rgds,

N.

doveadm backup -u username maildir:/tmp/Maildir

and then you can convert it back to sdbox after disabling sis by clearing the existing dbox files and running

doveadm -omail_location=maildir:/tmp/Maildir backup -u username sdbox:~/something

remember to take backups

Thanks for the quick response. I’ve tried a backup on 1 mailbox and indeed it stores the mails with attachments. I had tried it as an sdbox backup with the option to disable SIS but that didn’t seem to work.

Does anybody know if disabling SIS in the current setup will stop saving attachments to SIS but keep reading those that are already stored there?
