${ORANGE}DESCRIPTION${RESET}
|
|
Set a quota (storage limit) for an existing mail account.
|
|
|
|
The quota value is in bytes. You may use a unit suffix for convenience,
|
|
such as 10M for 10 MebiBytes (MiB). A value of 0 opts out of enforcing quota.
|
|
|
|
${ORANGE}EXAMPLES${RESET}
|
|
${LWHITE}./setup.sh quota set user@example.com 5G${RESET}
|
|
The account 'user@example.com' is restricted to a 5GiB storage limit.
|
|
|
|
${ORANGE}EXIT STATUS${RESET}
|
|
Exit status is 0 if command was successful. If wrong arguments are provided
|
|
or arguments contain errors, the script will exit early with exit status 1.
