What is Email Quota?

Email quota limits the maximum storage an email account can use. Once reached, new emails may be rejected until space is freed.

Method 1: Set Quota via HestiaCP Web Interface

Step 1: Log in to HestiaCP

https://YOUR_SERVER_IP:8083

Step 2: Navigate to MAIL Section

Click on MAIL in the top menu bar.

Step 3: Select Your Domain

Click on the domain containing the email account.

Step 4: Edit Email Account

Click the gear icon (⚙️) next to the email account.

Step 5: Set Quota

Enter the quota in MB (megabytes):

• 1024 MB = 1 GB
• 5120 MB = 5 GB
• 10240 MB = 10 GB
• Leave blank for unlimited

Step 6: Save

Click Save to apply the quota.

Method 2: Set Quota via SSH

ssh hxroot@YOUR_SERVER_IP -p 22

/usr/local/hestia/bin/v-add-mail-account admin example.com info P@ssw0rd 2048

The last number (2048) is the quota in MB.

Change existing quota:

/usr/local/hestia/bin/v-change-mail-account-quota admin example.com info 4096
