It is a Yahoo fault. Yahoo uses ant-spoofing scheme called DMARC, basically
telling the world "reject any mail with @yahoo From fields if they a not
coming from yahoo mail servers". Gmail honors that request and reject
deloptes messages to the list because they a coming from TDE servers.

The possible solutions are
a. (best) convince deloptes to resubscribe to list using different address
(actually many lists block subscriptions to them using yahoo addresses)
b. yourself resubscribe to list using an address which ignores DMARC
c. convince trinity maillists admins to change ezmlm settings so its "takes
ownership" of the messages (but this mangles From field among other
things, so many consider this to be a bad solution).
