Censoring email

It seems some mail to Apple’s iCloud has been caught in filters. Apparently, a few months ago someone sent a script to a iCloud user that contained the phrase “barely legal teen” and Apple’s filters ate it.
The amount of hysteria that I’ve seen in some places about this, though, seems excessive. One of my favorite quotes was from MacWorld and just tells me that many of the people reporting on filtering have no idea how filters really work.

And it’s not as if there’s a lack of good, free email providers with years of spam-blocking experience: Google, Yahoo, and Microsoft all spring immediately to mind. And—as far as we know, anyway—those services aren’t “helpfully” blocking any emails without telling their users.

“As far as [you] know” isn’t very far, actually. These services block email all the time and normally don’t tell users about it. Hotmail is notorious for accepting email and then just silently dropping it on the floor. Yahoo doesn’t usually drop mail after it’s been accepted, but is very picky about what mail it accepts. About the only company mentioned that accepts everything is Gmail. And even then I know Gmail does, very rarely, block at the IP level.
Filters are complex and filters are extensive. I hate it when filters are responsible for losing legitimate mail but it happens. I’m pretty sure, though, that outside of the testing for the phrase “barely legal teen” that this is a filter phrase that has an extremely low false positive rate.
That’s the crux of what’s useful in filters: how much bad mail does this stop while letting as much good mail as possible through. If a particular filter catches lots of spam, and blocks only a tiny bit of real mail, it will be a useful filter. If it doesn’t catch much spam but also doesn’t block much real mail, it might be a useful filter. If it catches too much real mail, it’s not a useful filter.
As it is, Apple and their filtering vendor have adjusted their filters such that mail with the phrase “barely legal teen” is again making it into the inbox.
I’m not really sure this is a win.

I'm on a blocklist! HELP!

Recently, an abuse desk rep asked what to do when customers were complaining about being assigned an IP address located on a blocklist. Because not every blocklist actually affects mail delivery it’s helpful to identify if the listing is causing a problem before diving in and trying to resolve the issue.

We're gonna party like it's 1996!

Over on deliverability.com Dela Quist has a long blog post up talking about how changes to Hotmail and Gmail’s priority inbox are a class action suit waiting to happen.
All I can say is that it’s all been tried before. Cyberpromotions v. AOL started the ball rolling when they tried to use the First Amendment to force AOL to accept their unsolicited email. The courts said No.
Time goes on and things change. No one argues Sanford wasn’t spamming, he even admitted as much in his court documents. He was attempting to force AOL to accept his unsolicited commercial email for their users. Dela’s arguments center around solicited mail, though.
Do I really think that minor difference in terminology going to change things?
No.
First off “solicited” has a very squishy meaning when looking at any company, particularly large national brands. “We bought a list” and “This person made a purchase from us” are more common than any email marketer wants to admit to. Buying, selling and assuming permission are par for the course in the “legitimate” email marketing world. Just because the marketer tells me that I solicited their email does not actually mean I solicited their email.
Secondly, email marketers don’t get to dictate what recipients do and do not want. Do ISPs occasionally make boneheaded filtering decisions? I’d be a fool to say no. But more often than not when an ISP blocks your mail or filters it into the bulk folder they are doing it because the recipients don’t want that mail and don’t care that it’s in the bulk folder. Sorry, much of the incredibly important marketing mail isn’t actually that important to the recipient.
Dela mentions things like bank statements and bills. Does he really think that recipients are too stupid to add the from address to their address books? Or create specific filters so they can get the mail they want? People do this regularly and if they really want mail they have the tools, provided by the ISP, to make the mail they want get to where they want it.
Finally, there is this little law that protects ISPs. 47 USC 230 states:

Amendment is futile, part 2

When Yahoo filed for dismissal of the Holomaxx complaint, they ended the motion with “Amendment would be futile in this case.” The judge granted Yahoo’s motion but did grant Holomaxx leave to amend. Holomaxx filed an amended complaint earlier this month.
The judge referenced a couple specific deficiencies of Holomaxx’s claims in his dismissal.
