I can't find an address to complain about the mailing list itself, so apologies but I'm posting directly to this list. Every time I post to this group, I get returned mails about OTHER subscribers' invalid accounts, like the one below.

Is this when you're replying to a post or creating a new post? If the former, and you're using reply-to-all, you'll be sending one message to the list and another directly to the poster of the message you're responding to.

Does the message come from postgresql.org or is the bounced email coming from these specific users when you include them in reply-all?
Thanks to both for your answers. But no -- It's for new posts. In fact, when writing the email that started this thread, it was only to pgsql-performance@xxxxxxxxxxxxxx (I double-checked by using emacs on my Thunderbird "Sent" folder), yet I still got another "undeliverable" reply along with your message:
This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed. martin@xxxxxxxxxxxxxxxxxxxxx
