I'd like to have the MARID information in a binary representation; the
current design favors a textual representation, with a lot of overhead.
libspf-alt currently byte-compiles all SPF records into a compact,
network portable, binary format that requires no text parsing.
I'll use hotmail.com as an example. You can see the information at:
http://www.lessspam.org/CallerIDPolicyWizard/?domain=hotmail.com
[37 records snipped]
The information occupies 537 bytes without tags.
In binary, that would be 185 bytes: 5 binary octets * 37 records.
Hotmail's email policy in:
XML: 1040 bytes
SPF: 776 bytes (XML * 1.32)
byte-compiled: 240 bytes (XML * 4.33, SPF * 3.23)
