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
