Hi @Scotty
I have since discovered that there is actually a way to do this. No fancy tick boxes, so it will take a few minutes of your time to setup.
First thing you need is the actual name of the folder on the server. To get that, right-click on the folder in eM Client and choose Properties. Copy the full folder name from the server location field.
Now go to Menu > Accounts and click on the Diagnostics tab for this email account.
In the Advanced Options field, we are going to add a parameter:
--imap-list-ignore-path "full folder path"
The folder name is case sensitive, so be aware of that.
It will look like this:
Now to finish up, click on Save & Close.
If you want to unsubscribe from more than one folder, you can do that as well. Just use something like this:
These parameters can be repeated as many times as you want but there must always be a pair:
--parameter "pattern" --parameter "pattern" --parameter "pattern"
Use a space to separate them.
There are also some other options:
--imap-list-ignore-path-starts-with "beginning of folder paths case sensitive"
--imap-list-ignore-path-regex "arbitrary regex pattern"
