I realize I can match on the Received header here, but that would require
creating an additional rule for each corresponding To rule. Perhaps there's
a way to combine them, or a tag that can be used for both?
the main question is what do you want to match.
I'm also aware of using ALL, but I think that may be too broad and may
catch instances that shouldn't be. Can someone explain how this rule works
and if something similar would apply to my situation?
header __HDRS_MISSP ALL:raw =~
