Hi Len,
We have been extremely busy over here, so I haven't had a chance to
circle back around, but for the record, volumes are still excessive, and
our team is detected malicious, easily identifiable spam on a regular
basis..

Do you want to circle around to talking about how we can create
automated reports of these for your company?

Hello Benoit and Hokan,
Thanks for pointing this out and I'm sorry you're still seeing what
sounds like a high volume of phish. I've asked our fraud ops team to
investigate this. In the future if you could send suspicious emails to
ab...@sendgrid.com <mailto:ab...@sendgrid.com> we will get this handled.
Feel free to CC me when you do this to make sure these are handled quickly.
We've instituted some self-limiting features on our front door that
should've decreased the overall volume of abuse. This is a stop gap
measure as we roll out some other countermeasures in the next few weeks.
Could you let me know if you have seen a perceptible drop in volume and
velocity between June and July when this was rolled out?
Again, I want to assure you that there is a massive effort happening
here to address the problems you are seeing. I'm happy to meet off list
and discuss this further and help you understand what we're working on
if that would be helpful. Again, thank you for your patience and please
don't hesitate to contact me when you see any of these issues arise.
Best,
-L

Subject: [mailop] Delisting request from sendgrid customer about ip
used in recent phishing campaign.

Hi List
o1678912x138.outbound-mail.sendgrid.net
<http://o1678912x138.outbound-mail.sendgrid.net/> [167.89.12.138] and IP
under
control of sendgrid was repeatedly involved in phishing and other spam
since June.
It ended up being blacklisted @ SWINOG.
Now a sendgrid customers complains to us, that his emails are being
rejected because of this listing.
But that makes me wonder: Doesn't sendgrid deal with such issues like
asking for delisting after blocking the sender itself and re-uses
recently (last phish received on 14. July) 'abused' ip addresses for
other customers?
Mit freundlichen Grüssen

I've instituted short-term blocks of Sendgrid mail several times this year
and started another today because it looks like as much as a third of the
mail they've sent us in the past week has been evil -- mostly phishing.
This is a problem for me because some of the mail Sendgrid sends is
wanted by my users. I'm thinking about just accepting it all and filing
it into user spam folders.
I see that the IP you mention, Benoit, is currently listed on the SBL and
Spamcop.
