Just X-Cart Australia offer 3 different webmail email clients for managing your mail. Below are the instructions for each one with regards to successfully permanently deleting email off the server. If you are exclusively relying on webmail for your email in order to avoid exceeding your mailbox quota and thus having your email bounce, we strongly recommend you correctly configuring webmail with regards to deletion of email.

If you are relying on a combination of webmail and local email client, or exclusively on an email client like Outlook or MacMail, please also read the article Deleting Mail from the Email Server: Using Your Local Email Client >>

Log into your webmail account

From left-hand navigation click on Options >> Mail >> Deleting and Moving Messages

On the next screen you need to do 3 things:

Tick the box that says “When deleting messages, move them to your Trash folder instead of marking them as deleted?”
From the drop-menu header ‘Trash folder:’ select the option ‘Trash’
Tick the “Display the ‘Empty Trash’ link in the menubar?”

Then click on ‘Save Options’

Your webmail is now set up that when you delete items from your Inbox by ticking the box next to an email you want to delete, that email will now go into the ‘Trash’ can.

From here you can either go into ‘Trash’ if you have accidentally put an item in there you actually want, and thus you can ‘move’ that email back into Inbox or the desired folder within Webmail

or

if you are confident that everything in the ‘Trash’ can be deleted then you can click on the ‘Empty Trash’ icon at the top of the page.

It may seem like double-handling, that when you delete an item it doesn’t get completely deleted off the server, but it gives users a chance to realise they have deleted an email by accident before it disappears for good. A bit like windows recycle bin.

Unlike other webmail Horde, you don’t have to set up anything from the onset as this mail client is already configured to move deleted items to ‘Trash’ with then the option of full deletion thereafter.

Open SquirrelMail

When you have an email to delete simply tick the box next to that email, and click on the ‘Delete’ button. By default the ‘deleted’ email is always forwarded to the ‘Trash’ can.

In order to remove the email completely from the server, you simply click on the word (Purge) to the right of the ‘Trash’ link.

Roundcube is set up to immediately forward ‘deleted emails’ to the Trash however initially the webmail client is set up to force you to manually go into Trash, highlight the actual email in the Trash can, and then click on the ‘Delete’ icon.

If you would like to automatically have your ‘Trash’ deleted fully from the server upon logout, simply go to Personal Setting >> Preferences
and scroll down and tick the box that says “Clear Trash on logout”.

* Warning: in setting up the Round Cube preferences like this you will not be able to retrieve any mail accidentally put in the ‘Trash’ can once you logout so be sure that no wanted email is ‘deleted’.
