How to reset mail quota

Forcefully recalculate email disk usage by rebuilding email account maildirsize files

E-mail disk usage information is normally updated automatically and no additional action should be necessary; however, it is possible to force e-mail disk usage to be recalculated using the following script via root SSH access:

Code:

# /scripts/generate_maildirsize --help
Usage: generate_maildirsize <modifier> <user>

This utility regenerates maildirsize files used by the maildir+
capable clients to assist in mailbox size calculations.

Modifier Flags:
    --confirm - This flag indicates that we really want to use this utility

    --allaccounts - This utility was originally intended to assist cPanel
        BoxTrapper with updating maildirsize files. Without this optional flag,
        generate_maildirsize will only operate on BoxTrapper enabled accounts.

    --rename - This optional flag indicates that the utility should rename
        individual message files to include the message size in the filename.
        This addition to the file name format is supported by Exim and greatly
        improves Exim's ability to update the maildirsize file.  POP3 accounts
        that store mail on the server may be forced to download their messages
        again if this option is used.

    --verbose - This optional flag turns on verbose mode for enhanced activity
        reporting to STDOUT.
 
    --onlyrecalculate - This optional flag will cause generate_maildirsize to
        only regenerate maildirsize files that are missing or are larger than
        5120 bytes.
       
    --help - display this message and exit.

To action upon e-mail accounts of a given cPanel user, specify the cPanel username as shown by the following example while ensuring to replace "$username" with the applicable cPanel login username:

Code:

# /scripts/generate_maildirsize --confirm --verbose $username

To action upon all e-mail accounts of all cPanel users, refer to the following example command; this may be entered via root SSH access:

Code:

# /scripts/generate_maildirsize --allaccounts --confirm --verbose

 

If you are sending an e-mail from Yahoo then I recommend referring to the official Yahoo help and support resources, as linked below:

• Yahoo! Mail | Help
• Yahoo! Mail | Yahoo! Mail Help

For e-mail accounts setup via cPanel, their disk quotas can be increased via the E-mail Accounts page, as noted via the following navigational menu path (with linked documentation): cPanel: Main >> Mail >> Email Accounts
