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?

N. It will prevent you from reading the mails completely.

That’s what I was afraid of. That means I need to convert all mailboxes all at once. I had hoped I could disable SIS and migrate 1 mailbox at a time.

As one who used Dovecot years ago without SIS (it still wasn't well baked) but was very interested in it, I'm curious why you want to stop using it?

I like experimenting with new technology and I liked the idea of SIS. I still think it is but I really don’t need it for the small mail-server I’m running and it adds a lot of complexity to the setup. There’s also AFAIK no tools to verify integrity or clean-up the SIS. So I’d like to go back to a simple storage solution.
