This is always problematic because ISPs won't tell you why they don't
like your mail because they consider that proprietary information.

There are a few things like DKIM signing your outgoing mail, publishing
SPF and ensuring full circle DNS that can help, but I see you already
are doing all those things correctly.

There is some info at <https://wiki.list.org/x/4030690>, but I think you
have all that covered.

The fact that this only affects one of the user's 4 subscriptions makes
it seem that this is something in his own configuration at the ISP.
Things like having the list posting address and the listname-bounces
address in his address book (or spam whitelist if any) can help.
