    Hi

    We're currently in the process of converting all our client's mailboxes from maildir to mdbox. As part of this process I've enabled mailbox compression which has shaved about 20% off our server storage usage, very happy with that result!

    However, I'm a little confused about how this is reflected to the customer in terms of quota usage. Taking an educated guess, I'd say the storage savings are reflected on their cPanel disk usage but the mailbox quota is still calculated using the uncompressed size.

    Is that correct?

    Hello,

    The compressed mails should be reflected in the email account's disk space usage (which is part of the overall account's disk space usage). However, note that the system will only compress recently created and delivered messages after enabling "Compress Messages". It does not compress all existing emails that have already been delivered.

    Thank you.

    I knew about that limitation so we've been converting from maildir to mdbox to overcome this. There's been a 20% reduction in total disk usage so compression is active, but the individual email account quotas don't seem to have changed to reflect this.

    For example I have one email account which on cPanel Webmail shows 6.97GB used, but when I tally up the backing files it shows 4.68GB usage.
