[FeatureRequest] Enable the use of wildcards for the fetchmail folder configuration

[NicolasGoeddel]

Environment & Version

• Docker Compose version v2.20.0
• MailU version 2.0

Description

When adding a fetchmail account you need to list all folders that should be fetched. In some cases this can be quite hard. For example my private mail box contains 227 folders.

Therefore my suggestion is to add the possibility to use wildcards for the folder list or add some kind of wizard which can list all the folders available so you are able to select all the folders that should be fetched.

Also sometimes folder names contain spaces. I am not sure if it is possible to add such folders to the list. In my private mail box I've got 65 folders with spaces. If spaces are not an issue then just ignore this paragraph.

I think this feature is out of scope. The "fetchmail" feature is primarily meant as a transition technology.
If you want to keep a remote email provider, you also can save a copy of the mails to be fetched in a separate folder and only fetch this folder using the fetchmail feature.
But maybe someone can provide a PR doing this in the users browser with help of some fancy POP3/IMAP-JavaScript-Library.
