Further than trimming, they should consider using neutral qualifiers for
generic mail sites. "include:spf.protection.outlook.com" can allow
office users to fully impersonate the save.ca domain. Setting
"?include:spf.protection.outlook.com" provides for not rejecting due to
-all, while not granting "pass".

This looks more like they’ve been testing several providers and ended up
with a large spf record that they might want to consider trimming.

*Subject:* [mailop] Love how people use SPF records.. Just for a chuckle..
host -t TXT save.ca
save.ca descriptive text "v=spf1 ip4:70.33.236.0/25 mx a
include:sendgrid.net include:thestar.ca include:thestar.com
include:spf.google.com include:spf.protection.outlook.com
include:spf.yahoo.com include:spf.aol.com include:amazonses.com -all"
... so.. basically hard block everything except 1/2 the internet..
I assume someone that likes spamming set THAT one up.. there is a good
reason that SPF have a maximum DNS amount of queries..
