Package: postfix-policyd-spf-python
Version: 1.0-2
Severity: grave
Justification: renders package unusable
postfix-policyd-spf-python freezes when using some DNS servers, for example:
nameserver 62.233.233.233
nameserver 87.204.204.204
nameserver 213.241.79.38
nameserver 213.241.79.37
Just paste some example (correct) input to policyd-spf command (new line at the
end), wait few seconds and press Ctrl+C. You'll see:
Traceback (most recent call last):

KeyboardInterrupt
When you change DNS to 8.8.8.8 everything is fine.
I checked this problem with 2 completely unrelated machines.
