Gmail deploys image proxy servers

This afternoon Justin Foster of LiveClicker posted to the OnlyInfluencers list asking about Gmail rewriting links. Sometime very recently (last 24-48 hours), we are seeing that Google made a change to Gmail such that all image URLs in the email content are replaced by a call to Google’s content caching service googleusercontent.com. For example, an […]

Open relays

Spamhaus wrote about the return of open relays yesterday. What they’re seeing today matches what I see: there is fairly consistent abuse of open relays to send spam. As spam problems go it’s not as serious as compromised machines or abuse-tolerant ESPs / ISPs/ freemail providers – either in terms of volume or user inbox […]

Private whois records hide spammers and help bring down a registrar

I’ve talked in the past about how many spam filters, ISPs and blocklists treat domains that are registered behind privacy protection.

Tabs were an attempt by Gmail to help Gmail users organize their mail, particularly programmatically generated email like social media alerts and marketing mail. While many of us took a wait and see approach, a number of email marketers […]

While they were down a while ago they were returning SERVFAIL for some DNS lookups, including MX lookups. For senders who have the DNS data in their recursive resolvers, this will have no impact. For senders who either […]

Overall, no one changes their filtering during the Holiday Mailing Season. On the other hand, many marketers do change their marketing strategies in ways that trigger […]

Unsubscribing from spam, part 2

Yesterday I posted about why the reasons a lot of people give for not unsubscribing from spam are mostly wrong. Unsubscribing from spam doesn’t seem to confirm your address and it doesn’t seem to increase your spam load. But does that mean you should unsubscribe from spam? I’m not sure about that. I’ve been working […]

Don’t unsubscribe from spam!!

Having been around the email and anti-spam industry for a while, I’ve just about seen and heard it all. In fact, sometimes I’ve been around for the beginning of the myth. One myth that seems to never actually go away is “unsubscribing just confirms you’re a real address and your address will get sold and […]
