What a mail client has problem with threading because of a tag in the
subject?
Threading is supposed to work based on "Reference:" and/or "In-Reply-To:"
headers. Only in lack of those, it falls back to subject (my mail client
also specially marks such messages in the thread to signal this fact).
I have no problems with threading regardless any tag being present in the
subject, its position, or lack thereof.
For excruciating correctness, no. The relevant header is called
"References:" (-> RFC 5322), and it's not "and/or", but "and", and
clients are supposed to create both. I wish mailing list drivers
enforced this and rejected anything that has something like Re: AW:
Re^99: or thereabouts in the subjects and not both References: and
In-Reply-To: headers, to get people to use proper tools for
participation in lists.
