We know that djbdns limits TXT records to 127 characters, while AOL is
able to publish a 210 length TXT record.

AOL record can be "compressed" with some simple regular expression
notation:

v=spf1 ip4:152.163.225.0/24 ip4:205.188.1(39|44|5[679]).0/24
ip4:64.12.13[678].0/24 ptr:mx.aol.com ?all

The original record is 210 chars while the "compressed" is 104.

That's quite a difference.  Is the regex compression in the example above
supported by SPF?
