More on

Quite a while ago, we SH editors discovered that when we send a rejection to a address, cox considers the rejection to be spam, so they send us a bounce message and don't deliver the rejection. For those unfamiliar with it, is a fairly major ISP, covering at least 20 US states. Their slogan on their main tech support page is "Just like a true friend, Cox is here for you 24/7."

When we first encountered the problem, we attempted to talk with the support people to (a) convince them that these messages aren't spam, and (b) find out what about the messages was causing them to be marked as spam. We were informed that since we weren't subscribers, they wouldn't talk to us. At all.

We eventually figured out that if I re-send the rejection from my personal account (rather than using our usual semi-automated system), it goes through. But that's a (minor) pain, and sometimes it takes a while for me to get around to it.

A couple of subscribers who submit to us, and who had therefore received delayed rejections, pestered support about it, but never (as far as I know) got anywhere.

The bounce messages say that we can make our message go through by writing to with subject line UNBLOCK. If you do that, you normally get an autoresponse from postmaster saying that if you're a customer, you should contact Customer Support.

I always try the UNBLOCK thing, but I don't think it actually does anything. But I've taken to sending the UNBLOCK request before sending the rejection, just in case that helps. Last month, for the first time, I got a query from about an UNBLOCK request; I very briefly and very politely explained the situation to them, and never heard from them again.

So this evening I sent an UNBLOCK request and then a rejection. And in response to the UNBLOCK, I got back . . . a bounce from postmaster. Saying:

This Message was undeliverable due to the following reason:

The user(s) account is temporarily over quota.


Please reply to <>

if you feel this message to be in error.

There's a certain purity and elegance to how self-contained that is--it's like a recursive definition. I'm tempted to reply to postmaster letting them know that the postmaster account is over quota, just for the fun of it.

Anyway. I guess my real point here is that if you're a customer and you submit to SH and you want a timely response, you may be best off getting a non-cox email account and submitting from that account.

If you submit from a cox account, you'll still receive a response from us; it just may take a while longer to reach you. Apologies; if I knew how to fix that, I would.

Oh, and if you happen to know anyone who works at cox, could you mention to them that their postmaster account is over quota?

    It can be extremely frustrating dealing with these sorts of problems where there are easy solutions, but those solutions cannot be simply implemented by the people who care about fixing the problems.

    On the other hand, I feel obliged to point out there is one obvious solution which is completely in your control, though non-preferred: You could accept all submissions from addresses, thereby eliminating the problematic scenario.

    I have to go sign up for a account now, just in case that turns out to be the solution…

    Addendum a year and a quarter later: at some point in the past year or so, Cox fixed the problem on their end; we haven’t had any trouble sending rejections to them in quite some time. I’m glad they did eventually fix the problem; too bad it took them many months to get around to it.
