I am looking for a way in gmail (technically google apps for business I think) to filter all email which is delivered to an address using plus addressing. I want to tag all email to
firstname.lastname@example.org as one thing and
firstname.lastname+[anything at all here]@example.com as something else.
I was intrigued to discover that whilst searches for
email@example.com only returned messages to that specific address, searches for
firstname.lastname@example.org included all plus addressed messages in the results, which seems slightly inconsistent, but I assume is by design.
As far as I can tell what I'm trying to do isn't possible, due to the lack of support for wildcard searches, but I thought I would check that there isn't another way to do it. I don't think this question is a duplicate of any of the following, but if anyone feels that it is, I'm sorry and feel free to shut this down.
The question How can I filter incoming email based on plus addressing in Gmail? notes that you can filter a specific plus address eg
The question Wildcard search in Gmail notes that there is no real support for wildcard searches in gmail filters.
The question Filter email based on Gmail plus operator, with wildcard seeks to use a wildcard search to filter a set of plus addresses eg
And concludes that this is not possible. I think my question is different as I am attempting to filter all plus addresses messages, rather than a set of them, however I suspect that the answer to my question is no for the reasons listed here.
