Speaking of SendGrid.. (Again)
BTW, our guys policy, on detection of 'phishing' the IP is posted to
RBL's.. otherwise it is probably just scored a little higher..
But does anyone know these guys? Looks like they have bought or used a
bad mailing list, or they have a sign process being abused heavily..

I've been very saddened. Sendgrid was a reputable ESP that has fallen
from grace. About 6-7 months ago, we started seeing pretty large
amounts of spam from them.
Exactly - this tracks with the timeline when a) they ceased being
certified by us, b) certain key people who *had* been involved with
making sure that SendGrid did the right thing left, and then c) they
were acquired by Twilio. Acquisitions of reputable players in the
email space generally lead to a decline in how white hat they are,
because of course the acquirers are almost always only (or at least
primarily) interested in a return on their $ investment (witness Habeas).
If, after months of abuse, receivers continue to take the attitude that
the relatively small amount of wanted mail coming from Sendgrid is an
obstacle to a complete block, we are simply acting as enablers and there
is no incentive for them to get a handle on the problem.
IMHO, Sendgrid doesn't consider it to be a problem, they consider it to
be a feature. As long as the spammers' and phishers' checks don't bounce
they're happy to accommodate them. As long as the rest of the Internet
continues to take their abuse, they will continue to dish it out.
