E-Mail Issue with SquirrelMail ERROR: Could not append message to INBOX.Sent

[WHUK-Sarina]

While sending emails from Squirrelmail in cPanel you might face following error:

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

ERROR: Could not append message to INBOX.Sent.
Server responded: Error in IMAP command received by server.

ERROR: Connection dropped by IMAP server.
Query: LOGOUT

This error is basically faced due to the tmp folder missing in the respective folder.
To sort this error you can follow following simple steps.

Go to the folder: /home/username/mail/Domain.com/xyz/.Sent

[root@server ~]# cd /home/username/mail/Domain.com/xyz/.Sent

Now create the tmp folder in this directory ans assign appropriate ownership and permission of 0700

[root@server .Sent]# mkdir tmp
[root@server .Sent]#chown username.username tmp/
[root@server .Sent]# chmod 0700 tmp/

Now try sending emails from Squirrelmail. It should not issue any errors.

Note:
Replace username with appropriate cPanel username and Domain.com with appropriate domain name.
