How do I create a message filter with multiple nested rules?
In Thunderbird, you can create message filters with multiple rules like so:
rule1 AND rule2 AND rule3 AND...
or
rule1 OR rule2 AND rule3 OR...
but I want to be able to make more general boolean queries for rules like:
rule1 OR (rule2 AND rule3) OR rule4 OR (rule5 AND (rule6 OR rule7))
Other applications have this ability by allowing the "+" button in filter creations to create another block of "match ALL/ANY of the following" nested under an existing rule.
Can this be done in Thunderbird?
Thanks!
