More Sendgrid trouble?

[Kris Deugau]

Is anyone else seeing intermittent FNs on mail sent through Sendgrid 
where the nominal sender has a default welcomelist_* entry?

Today's spample is a Mcafee scam email, pretty clearly sent through 
Intuit's Sendgrid account based on the rDNS.  On testing in my sandbox 
it was only allowed through due to the stock welcomelist entry for Intuit.

Not 100% sure whether this is a Sendgrid issue, or an Intuit issue - 
I've reported the message to both of them, for whatever good it will do.
