strip of some filename chars in folder_format setting

[Oliver Graute]

Hello list,

how can I strip of the first 23 chars of my filename string in the
folder_format setting?

set folder_format = "%2C %t %N %d %f"$

so that:

11   N Apr 12 08:19 =usern...@provider.com/Mailinglists.mutt-users/

looks like this

11   N Apr 12 08:19 Mailinglists.mutt-users/

Best regards,

Oliver
