Hi,

There seems to be IP/network entries missing from domains with longer TXT SPF records, for example when using icloud.com it is only picking up the first 11 records and missing the remainder from the record, although the returned TXT string seems to be broken:

python3 spf_to_greylist_whitelists.py --debug icloud.com

* 1 mail domains in total.
        + [icloud.com]
                + SPF -> v=spf1 ip4:17.41.0.0/16 ip4:17.58.0.0/16 ip4:17.142.0.0/15 ip4:17.57.155.0/24 ip4:17.57.156.0/24 ip4:144.178.36.0/24 ip4:144.178.38.0/24 ip4:112.19.199.64/29 ip4:112.19.242.64/29 ip4:222.73.195.64/29 ip4:157.255.1.64/29
