Ok, so I found the mail paper background here:
https://github.com/Gethe/wow-ui-text...ive/Stationery.
But I can't find the lines between the MailItemFrames:

When I replace all textures within the MailFrame folder it still seems to be generated.

From the
code it should be related to the MailItemBorder but changing doesn't affect it.
Any1 know how to hide or replace it?
