Taking a look on my SME 10 spamd logs, each and every pyzor mail check after March 22nd, 8am CET seems to fail with a timeout, for example:
Apr 21 08:24:01 mail spamd[10172]: spamd: connection from 127.0.0.1 [127.0.0.1]:42550 to port 783, fd 5

Has the Pyzor network gone down permanently? If so, should I "clean" SME configuration somehow, with relation to Pyzor setup?
There's always the chance that the government WAN I'm in blocks somehow pyzor access...
EDIT: Some additional testing from the same LAN shows that public.pyzor.org is up, but port 24441/TCP is blocked:
