Mailbox Conversion in WHM

Mailbox Conversion in WHM

MDBox is the most promising and demanding feature in the latest cPanel and it is the most appealing feature. There is a huge benefit of converting from Maildir to MDBox.

Both Maildir and MDBox are the storage formats used by the mail application on the cPanel server. There are lots of differences, but the most important one is that email stored with Maildir uses a simple 1-to-1 format, while MDBox uses a many-to-1 format. For the simple cPanel user it makes no difference at all, but for large account it is really important. Compressing one mail and to be stored in a single file will lower inode usage as well as the disk space usage.

Meantime we can migrate, transfer account by taking the backup can be done in a small fraction of time.

Mail operations do not go offline during conversion. How long conversation takes will depend on the number of accounts and amount of email, but on a typical shared server, it’s complete in well under an hour.
