Another major function setting that applies to POP3 accounts that is not as important with IMAP is "leave a copy of mail on the server" (or similar).
Unless you are in some sort of logged system you can ignore this setting for IMAP and leave it off
If you are using only one system you can also do the same with POP3.
In a case where you have a main system at home and a mobile device, (laptop), which are both using POP3 then I advise the following ...
Set the "leave a copy of mail on the server"to "on" on the laptop and set it to "Off" on the home system, this will mean that if you are away from home you can work on your email in TB but no deletions will take place until they are actioned on the Home system (built in backup). The system may be expanded for multiple devices but should only ever have one "Home" device that has the setting such that things are actually changed on the server
