Huh. Very odd.
I sent my 2 messages on getting an older fail2ban version working from inside the Yahoo web mail page...it doesn't get more Yahoo than that. (smile).
I don't think there's anything I can do to prevent this, is there?

I do not think the list was down, though all mail from you has ended up in my spam folder
