October 2016: The Month in Email

We’ve returned from London, where I spoke at the Email Innovations Summit and enjoyed a bit of vacation. My wrap-up post also mentions an article I wrote for the Only Influencers site, which looks at questions I get asked frequently: “Why does spam make it to the inbox and our legitimate marketing email doesn’t? Should we just copy their tactics?”

In industry news, Yahoo caught our attention for two surprising moves: disabling forwarding and — much more disturbing — creating software for intelligence agencies to search customer email.
Some legal updates this month: The Second Court of Appeals upheld an earlier ruling that companies are in fact liable for the activities of their affiliates, including spam and fraudulent claims. This is important, as we often see spammers and cybercriminals use affiliates to distance themselves from these activities. We also saw another fine assessed for a violation of CASL, and noted with appreciation the transparency and thoughtful process that the Canadian Radio-television and Telecommunications Commission (CRTC) demonstrates in explaining their actions.
Another excellent report is the one created by the Exploratorium to explain their recent experience with being phished. It’s a good piece to share with your organization, in that it reminds us that these cybercriminals are exploiting not just our technology but our trust-based connections to our friends and colleagues. It’s important to raise awareness about social engineering as a part of information security. And speaking of email security, we were delighted to note that André Leduc received the 2016 J.D. Falk award this month at M3AAWG for his excellent work on this topic. It’s a fitting legacy to our friend, J.D., who died five years ago this month. We miss him.
Finally, we’d be remiss in observing Halloween without a post about zombies. Feel free to read it aloud in your spookiest voice.

The J.D. Falk award 2013

M3AAWG awarded the second J.D. Falk award today in Montreal. The winner was Gary Warner from the University of Alabama.
Gary has been involved in fighting abuse and online crime since the 1990s. He developed the Center for Information Assurance and Joint Forensics Research at the University. This is an education program that not only teaches students about online threats and how to fight them, but collaborates with both industry experts and law enforcement.

May 2014: The month in email

It’s been a busy and exciting month for us here.
Laura finished a multi-year project with M3AAWG, the Messaging, Malware and Mobile Anti-Abuse Working Group (look for the results to be published later this year) and continued working with clients on interesting delivery challenges and program opportunities. Steve focused on development on the next version release of Abacus, our flagship abuse desk tool, which will also be available later this year.
And as always, we had things to say about email.
The World of Spam and Email Best Practices
We started the month with a bit of a meta-discussion on senders’ fears of being labeled spammers, and reiterated what we always say: sending mail that some people don’t want doesn’t make you evil, but it is an opportunity to revisit your email programs and see if there are opportunities to better align your goals with the needs of people on your email lists. We outlined how we’ve seen people come around to this position after hitting spamtraps. That said, sometimes it is just evil. And it’s still much the same evil it’s been for over a decade.
We also wrote a post about reputation, which is something we get asked about quite frequently. We have more resources on the topic over at the WiseWords section of our site.
Gmail, Gmail, Gmail
Our friends over at Litmus estimate Gmail market share at 12%, which seems pretty consistent with the percentage of blog posts we devote to the topic, yes? We had a discussion of Campaign Monitor’s great Gmail interview, and offered some thoughts on why we continue to encourage clients to focus on engagement and relevance in developing their email programs. We also wrote a post about how Gmail uses filters, which is important for senders to understand as they create campaigns.
SMTP and TLS
Steve wrote extensively this month about the technical aspects of delivery and message security. This “cheat sheet” on SMTP rejections is extremely useful for troubleshooting – bookmark it for the next time you’re scratching your head trying to figure out what went wrong.
He also wrote a detailed explanation of how TLS encryption works with SMTP to protect email in transit, and followed that with additional information on message security throughout the life of the message. This is a great set of posts to explore if you’re thinking about security and want to understand potential vulnerabilities.
DKIM
Steve also wrote a series of posts about working with DKIM (DomainKeys Identified Mail), the specification for signing messages to identify and claim responsibility for messages. He started with a detailed explanation of DKIM Replay Attacks, which happens when valid email is forwarded or otherwise compromised by spammers, phishers or attackers. Though the DKIM signature persists (by design) through a forward, the DKIM specification restricts an attacker’s ability to modify the message itself. Steve’s post describes how senders can optimize their systems to further restrict these attacks. Another way that attackers attempt to get around DKIM restrictions is by injecting additional headers into the message, which can hijack a legitimately signed message. If you’re concerned about these sort of attacks (and we believe you should be), it’s worth learning more about DKIM Key Rotation to help manage this. (Also of note: we have some free DKIM management tools available in the WiseTools section of our site.)
As always, we’re eager to hear from you if there are topics you’d like us to cover in June.

Yahoo disabled forwarding

Al posted about this over on his blog earlier this week. Yahoo has disabled the ability to forward email from one Yahoo account to an email account on a different system.
There is, of course, all sorts of speculation as to why forwarding has been disabled including speculation this has to do with holding on to accounts during the Verizon purchase. It’s certainly possible this is the case.
However, forwarding email is hard. Forwarding email on a large scale can result in spam blocks and delivery problems. It’s such an issue M3AAWG published a forwarding best practices document. It’s possible that Yahoo is making some changes on the back end to better implement the best practice recommendations. I don’t know, but it’s possible that Yahoo is telling the truth that they’re improving technology.
