Creating an "Add inbox rule" from "Reply to" field

[serrq]

I am in a very special case: my sender is hidden behind a "service", so its "From" field is the same for thousands of other news sources, and its (technical) "Sender" field is new in each email I receive from it.

Solution: attacking the "Reply to" field creating a rule beginning from that field.

You can create an inbox rule based on a header, does this help? it's a bit of a workaround though
