Today is world IPv6 launch day. A group of ISPs, network hardware manufacturers and web companies permanently enabled IPv6 for their products and services.
What’s this got to do with email? According to a post on the NANOG mailing list the very first email to arrive at the Comcast IPv6 mailserver was received a minute after the server was turned on. This email was spam and was caught by Cloudmark’s filters.
Comcast goes on to assure readers that more mail came in and not all of it was spam.
But, yes, the first email sent to Comcast over IPv6 was spam. Welcome to the future.

Much like every other day, I got some spam today. Here’s a lightly edited copy of it.
Let’s go through it and see what they did that makes it clear that it’s spam, which companies helped them out, and what you should avoid doing to avoid looking like these spammers…
Working as intended

There’s a certain type of sender that thinks every ISP block or email delivered to the bulk folder is a false positive. They’re so sure that the filters aren’t actually supposed to catch their mail that they’ll spend any amount of money and do every possible thing to get their mail to the inbox.
The problem for these senders, though, is that their mail is exactly the type of mail filters are designed to catch. They’re sending mail without recipient permission. I’m not talking about the lists that get a few typos or problem addresses on them. I’m talking about senders that buy and trade mailing lists. I’m talking about senders that don’t believe they have to have permission to send mail.
This mail getting filtered is a sign that the filters are working as intended. They’re keeping the unsolicited email out.
A lot of us take for granted that all commercial mail, at least that isn’t selling fake watches or herbal viagra, is always sent with permission. But there’s an awful lot of mail out there that doesn’t even have a minor fig leaf of permission. Filters stop that mail. And senders have very little recourse when they do.
