SPF Record verification fails for domains starting with "all"

[ricco386]

If a SPF record has string all in domain, the regular expresion fails with error:

The domain spf.all does not exist

For example domain: allianz.sk has a SPF record: "v=spf1 ip4:91.206.87.24 ip4:91.206.86.232 ip4:91.206.87.210 ip4:208.73.7.175 mx include:mcxplatform.de include:spf.allianz.com -all" which seems to be correct, but executing: spf = check_spf('allianz.sk') results with an error.

Problem seems to be a regex in spf.py on line 42:

AFTER_ALL_REGEX_STRING = r"\ball\s*[^\s]+"
