Conversion to mdbox

Hello @fonginator,

The "--delete-old-format" flag is available as part of the conversion scripts to ensure the old files are removed after a successful conversion. It's documented at:

The Mailbox Format Conversion Scripts - Documentation - cPanel Documentation

There's no native feature that will allow you to restore emails directly, but we have a feature request open that I encourage you to vote for at:

Adjust restore account to use dsync

However, aside from an official feature, you can use the dsync utility manually from the command line. Here's an example:

Code:

dsync mirror -u user1 'mdbox:/path/to/backup/cpuser1/homedir/mail'
dsync mirror -u user1@domain.tld 'mdbox:/path/to/backup/cpuser1/homedir/mail/domain.tld/user1'

It's true that you may lose emails due to corruption if the system does not have backups (or emails are delivered after the most recent backup generation), but the amount of emails lost would depend entirely on the level of corruption. That said, we've not seen any issue with corruption in testing thus far.

Thank you.

 

Did you choose "Keep old mailbox files. This option maintains the old files in case of an error. You must remove these files manually." when converting the mailboxes via WHM? If so, here's a quote from our Mailbox Conversion document explaining where this data is stored:

We've not seen any issues with corruption, but you are correct that backups would include the emails (though you could lose any emails delivered between the time the most recent backup finishes and when the corruption begins).

Thank you.
