antispam M3AAWG Position on Selling Email Address Lists [PDF]

The practice of selling, buying or sending to lists of purchased email addresses – whether business to business (B2B), business to consumers (B2C) or other categories, is in direct violation of M3AAWG core values.

antispam 800+ Million Emails Leaked Online by Email Verification Service

On February 25th, 2019, I discovered a non-password protected 150GB-sized MongoDB instance. This is perhaps the biggest and most comprehensive email database I have ever reported.

antispam Spam does not bring us joy—ridding Gmail of 100 million more spam messages with TensorFlow

1.5 billion people use Gmail every month, and 5 million paying businesses use Gmail in the workplace as a part of G Suite. For consumers and businesses alike, a big part of Gmail’s draw is its built-in security protections. Good security means constantly staying ahead of threats, and our existing ML models are highly effective at doing this—in conjunction with our other protections, they help block more than 99.9 percent of spam, phishing, and malware from reaching Gmail inboxes. Just as we evolve [...] [more]

antispam Wer steckt hinter der Flut illegaler Werbemails?

Eine neue Form professionell wirkender Werbe-Mails soll die Empfänger in die Arme von Versicherungsmaklern treiben.

Im Gegenzug, verspricht der Absender, würde er sein Vermögen [...] [more]

At the 2018 Open Source Summit Europe, Giovanni Bechis talked about that release and those that will be coming in the near future.

antispam Hacking Gmail’s UX with "From" Fields – Another Phishing Vector

Tricksy From Field. As you might see in the above screenshot there are two emails in the Sent folder despite them being addressed to and received by account holder. We double checked the email headers to see if what we saw in the displayed From/To fields was correct, and as you can see in the screenshots the “From” field has a weird structure: [...] [more]

antispam What do Postmasters see daily?

Some common questions Postmasters field from senders are, “What happens to all the Postmaster tickets we submit? Does anyone look at them? What’s even going on there?” Before coming to 250ok, I worked as an AOL Postmaster. So in short, I know some stuff, and I’m happy to share what I can. So, we could go straight to the short answer, but… what’s the fun in that? Instead, let’s go on a journey together. Let’s start by getting a better understanding of what’s going on at the Postmaster. Even though [...] [more]

antispam Kurz erklärt: Brand Indicators for Message Identification

Phishing beschäftigt seit Jahren die IT-Branche und die Anwender. Ein Verfahren namens BIMI soll die Lage verbessern, indem authentifizierte Nachrichten ein verifiziertes Logo erhalten.

antispam DMARC adoption rates very low across most industries.

This year, we made it a priority to analyze the adoption of Domain-based Message Authentication, Reporting & Conformance (DMARC) in industries using email as a key means of communication and business growth. We looked at the domains of the SaaS 1000, top law firms, nonprofit organizations (NPOs), higher education institutions, top Chinese brands, and e-retailers to better understand how seriously they take email authentication. Unfortunately, not one industry reviewed had even a 50% adoption rate, [...] [more]

antispam Google moves gmail.com to "quarantine" DMARC policy (for subdomains)

Gmail warned us that a more restrictive DMARC policy was coming, didn't they? That warning came all the way back in 2015. They said that "p=reject" was coming. Maybe it still is -- we're not there yet, but this appears to be a step in the right direction. Today's update: For subdomains under gmail.com and googlemail.com, they've implemented a "quarantine" DMARC policy. [...] [more]

antispam Minimal DMARC

What if your recipients have been happily forwarding the mail you send to them to internal mailing lists and alternate accounts and so on for decades? And that forwarding is the sort that’s likely to break DKIM signatures as well as break SPF? And while everyone would advise you not to deploy DMARC p=reject, or at least to roll it out very slowly and carefully with a long monitoring period where you watch what happens with p-none, you have to deploy p=reject real soon now?

antispam How Apple's DMARC Changes Affect Email Senders

Domain-based Message Authentication, Reporting, and Conformance, otherwise known as DMARC, is a protocol and best practice for email deliverability that continues to grow within the email marketing world. Email mailbox providers continue to update their DMARC policies and we want to make sure email senders are aware of these changes and what it means for their programs. Yahoo and other inbox providers have done it previously, and Apple is the most recent inbox to take this step. This update it one of [...] [more]

antispam DKIM: Using Cryptography to Protect Your Brand From Fraud

Have you ever received an email that appeared to come from your bank, colleague, or company you've done business with, only to discover that it was spam? Even to the most discerning eyes, some of these fraudulent emails can look nearly identical to their genuine counterparts. For cybercriminals, masquerading as recognizable individuals and organizations is a tactic that makes profiteering from email scams a very lucrative venture. [...] [more]
