I don't know anyone there that I know of, but whoever they are they are capable of advertising on many of the TV channels we watch fairly regularly. So, maybe bad signup process, hard to say without knowing more. When you visit their Web site to check it out you're forced to sign up or login, so that's probably the human factors issue that's driving that. -- hesketh.com/inc. v: +1(919)834-2552 f: +1(919)834-2553 w: http://hesketh.com/ Internet security and antispam hostname intelligence: http://enemieslist.com/ ___ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
Re: [mailop] [External] sendgrid.net
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.. 149.72.129.15 (S,M)31 o1.sg.e.zulily.com 149.72.129.150 (M) 42 o2.sg.e.zulily.com 149.72.129.152 (M) 37 o3.sg.e.zulily.com 149.72.164.60 (M) 45 o4.sg.e.zulily.com 149.72.177.54 (M) 38 o5.sg.e.zulily.com 149.72.177.55(M) 42 o6.sg.e.zulily.com 149.72.202.44 (M) 37 o7.sg.e.zulily.com 149.72.208.230 (M) 40 o8.sg.e.zulily.com On 2020-09-25 12:00 p.m., Jay Hennigan via mailop wrote: On 9/25/20 11:50, Anne P.

About 6-7 months ago, we started seeing pretty large amounts of spam from them. I've personally tried reaching out to Twilio / Sendgrid leadership to alert them to the issue. The KAM.cf ruleset has rules that mark sendgrid higher due to the proclivity for phishes. Krebs as done an article on it: https://krebsonsecurity.com/2020/08/sendgrid-under-siege-from-hacked-accounts/ mailop, the SA mailing list and others have all discussed the issue for months. Invaluement released a plugin / list for this issue as well - See https://www.invaluement.com/serviceproviderdnsbl/ Until Sendgrid acknowledges and works to resolve the issue, I must recommend that they are avoided.
