ERROR: Could not append message to INBOX.Sent.

While sending email from cPanel webmail following error appearing.

ERROR: Could not append message to INBOX.Sent.
Server responded: [alert] Cannot create message – no write permission or out of disk space.

FIX:

Check if tmp directory is present under directory /home/cPanel-Username/mail/Domain-Name/email-account-username/.Sent
If not then create it and change ownership for directory tmp to cPanel-Username.cPanel-Username

Note:

Replace cPanel-Username, Domain-Name and email-account-username with your actual names.

Thank you
