I have already contacted postmaster and they are aware, however you add very good point. Somehow I knew it but it's the way you put it that made me realize: the emails are sent in bulk to gmail (to many or all recipients for a single copy at once). The mail header even shows this, listing the first recipient followed by "+ 99 others". If it's delayed for all because of a single recipient that can only be because the 4xx error is returned at the end of the DATA command (rather than on a specific RCPT TO command), so no way for the sender to retry that single faulty address alone later. I'm not sure if their software allows it but I suggested sending to a single recipient at a time for gmail, that would solve the issue. In the meantime what I did is switch my subscription to another email using a forwarder address on a domain I own - I still haven't received all the backlog but at least I'm getting new posts timely now.
