Hi Mat
Probably top-level .xyz is a bad choice. At least in the past, those domains
was source of only spam, so we decided at some point to block all of .xyz
domains (sure not best practice, but since we only filter for ourself and know
our customers, we never had any customer using .xyz

And I realized it's silly to hide domains, so here it goes
* sender domain - kowalski.xyz
* recipient domain where the problem was first observed - amag.ch
* my 2nd domain which reproduces the problem - microsoft365.kowalski.xyz
Cheers!

Have you tired talking to supp...@proton.me? They are usually quite
responsive. If that doesn't work DM me.
