Disabling an email account

How can a particular email account be ‘disabled’ temporarily. Note that the email account should not be ‘deleted’ ? Is this possible at all via cPanel?

There is no direct functionality in cPanel at the moment for this. This feature might be added at a later stage.
However, you can achieve this functionality by modifying a few entries via SSH.

Comment out the entries related to the particular email account in the following locations:
/home/user/etc/domainname/passwd
/home/user/etc/domainname/shadow
/home/user/etc/domainname/quota

Make sure that you just comment them and NOT delete them as you might need them back later.

DNS, email or any other functionality can be handled through ‘Feature Lists’ in WHM. Just go to WHM >> Feature Manager. Edit/create a feature list and enable/disable functions as required. Assign this ‘feature list’ to the particular ‘package’ which is assigned to the accounts.
