I wanted to migrate some maildir accounts to sdbox using dsync and take advantage of Dovecots alt-storage option.
I understand that I need to modify users mailbox location and format in SQL table mailbox
Can anyone tell me the best way to specify the alt-storage path for dovecot in the mailbox table?

Thank you

The "vmail.mailbox" table doesn't have a column to store such meta data, you have to update dovecot.conf directly.

It appears the mails under this directory are being stored as sdbox correctly however the vmail.mailboxfolder sql setting  is being ignored.

Could you please show me the full content of /etc/dovecot/dovecot-mysql.conf? (Remove SQL password before pasting).

Re: Migrate to sdbox and add alt-storage to dovecot

Sorry, I had found the error in that file.
It had Maildir hardcoded in the concat statement instead of the mailbox sql field.
I have changed it to:
user_query = SELECT \
            '%u' AS master_user, \
            CONCAT(mailbox.storagebasedirectory, '/', mailbox.storagenode, '/', mailbox.maildir) AS home, \
            CONCAT(mailbox.mailboxformat, ':', mailbox.storagebasedirectory, '/', mailbox.storagenode, '/', mailbox.maildir, '/', mailbox.mailboxfolder) AS mail, \

If i add a column to mailbox table, "dboxaltstor varchar(50),default NULL"
and only populate it for dbox users like ":ALT=/nfsmnt/%d/%n"
Is it ok to append it to the above statement in order to achieve the alternate storage?
I tried to add it to dovecot.conf but the sql overides the parameter

I did a little testing and it appears to work as long as the altstore field does not contain variables such as "%d or %n"

You can add the "ALT=" in dovecot.conf, parameter "mail_location =".

"%d" and "%n" should be supported by Dovecot. sad
You'd better report this bug to Dovecot team.
