i want a guide about creating wildcards so that, for example, all messages from mozilla.org are allowed to show remote content

This link helps you to solve the issue.

This article provides the generic way of accepting remote content. what i need is through preferences > privacy > mail content > exceptions, to add exceptions that allow an entire domain somehow like *.mozzila.org. I have seen a way to do it, after allowing the usual way. ([*].mozilla.org) but it doesn't work. I just need to get rid off setting in the standard way and not be asked for allowance from *.intel.com for example that uses a ton of subdomains. There must be syntactic rules documented somewhere but i cannot find a relevant answer in the thunderbird support pages.
