Hi, I would have posted this on this previous question by the same name https://support.mozilla.org/bm/questions/1266115 However it has been closed from further discussion despite being the top search google link for "thunderbird filter contains wildcard" And what I wanted to say is that This should long have been core functionality It is not even apparent when you make the filters, that wildcards (*) don't work So you make a ton of filters and they're silently broken !!! I find the general filter creation process very cumbersome, almost almost every setting has to be changed every time, the main window, locks so you can't copy-paste from it mid-filter-creation and many many other quirks that make each filter creation an annoying 20 steps process, core among which, is the inability to create a destination folder on the fly while creating the filter ! But yeah, no wildcard support is kind of crazy for example I want to put all emails from pizzahut in a folder But they randomly change their From URL to @a.pizzahut.ca @b.pizzahut.ca @c.pizzahut.ca @d.pizzahut.ca @e.pizzahut.ca @f.pizzahut.ca It's like they know the filters can't wildcard ! they is super annoying !!
