Hello Bill,

OK, I've looked again and those were the headers of the message sent
by procmail and not the ones on the incoming external email which will
follow.
I don't see any evidence of Shopify in those headers either and at first
I suspected that maybe the mail isn't really from Shopify, since there
are indicators of both Sendgrid and Klayvio in those headers.
As it turns out, apparently Shopify has outsourced to Klayvio who has
outsourced to Sendgrid. It's not clear to me whether the full message
would hit SHOPIFY_IMG_NOT_RCVD_SFY, since there are multiple ways for
the body or headers to be exempt from the basic "Shopify-hosted image
without Shopify in headers" concept of the rule, but I will shortly add
a sub-rule to detect Klayvio and prevent this class of FP.
As to the version, it's the lastest version in the CentOS repos.
And yet, it remains obsolete.
It's probably not *dangerous* to be using SA 3.4.6-RedHat. They backport
security and some bugfix changes, so it's not broken exactly. It's just
not the SA that we still support and it's not ever going to have all of
the features added since 3.4.6, nor some of the more complicated
bugfixes.
It is possible to upgrade to 4.0.2 using CPAN but there are definitely
reasons not to do so if you value simple clean system management.
