I suppose my last mail has already been blocked, however, if it should
it ever through, it turned out to be a fetchmail issue, causing a loop
in turn bouncing mails with a 550.

I've just made a configuration mistake that'll likely put me on all
blacklists in this universe. But asides that, I guess I have a more
question about the way opensmtpd handles recipient verification.
Accepting mails for user known to the system works, but what I
though about, are mailing lists. And probably, also mails to be
[B]CC could be affected.
As those are not directly adressed to any account known to the
f.e "email@example.com", opensmtpd rejects them with an "550 Invalid
That is a problem I have currently no idea on how to deal with this.
