Hi,
Anybody else seeing increase phishing through sendgrid? They look
fairly convincing.
A few paypals, and a few amazons.
I thought sendgrid were ok? Has somebody leaked a big pile of
sendgrid usernames and passwords or something?

Hi everyone,
Is anyone from SendGrid on-list that can help with an abuse report that has
gone unanswered?
We have two tickets with SendGrid that have *no response: *4218173 and
4278230.
This fraud account is phishing our users, so there's no reason SendGrid
shouldn't be able to suspend / ban

mean it should be doing (or be good at) the other.

that reply code 551 is
precisely for that. Still, the rest of security considerations apply.
Nonetheless, I'm sure SendGrid could have the initial proofpoint MTA
forward ab...@sendgrid.com to a separate domain, thus avoiding Google
filters and the need of having the MTA a custom c
m is sending quite
a bit to our spamtraps too.
Unredacted headers are not forthcoming as we're not interested in
revealing spamtraps.
I should also say that I find it offensive for SendGrid support employees
to ask for the same in support responses, which seems to be the new normal
these days.

Hi,
Anybod
Hello,
Ryan from Sendgrid here hoping to speak with Symantec off list. Apparently
something in our headers is upsetting/breaking your system?

About two hours ago, we started seeing a significant uptick in "554
Transaction failed" responses from Microsoft domains. Across all senders.
Anyone else seeing this? If I remember correctly, this came up back in Feb.
as well.

Hello,
SendGrid has a client who is also using an IP on google's network. This IP
is blacklisted on an SBL.
Does anyone know how to get google's attention to reach out about a
Spamhaus SBL?
Thanks for everyones time and help!
