Open letter to


For the second time now, you’ve started throwing our license e-mails on the floor, in spite of them being accepted by your mail servers:

Mar 28 09:21:37 xxxxx postfix/smtp[13068]: 10C9320070: to=,[]:25, delay=1.5, delays=0.24/0.01/0.62/0.6, dsn=2.0.0, status=sent (250 2.0.0 1MMc1v00M3pvRLq01MMcTP mail accepted for delivery)

Note that it says “accepted for delivery”. You didn’t deliver it.

I’m fed up of explaining to your customers that you’re the cause of this problem. I’m fed up of being told it can’t be you (and quite often getting lots of abuse or complaints that we haven’t sent license details through). What I’ve done instead is I’ve added a page to our support system listing e-mail providers customers shouldn’t use. You’re on it. In fact, you’re the only ones on it. Congratulations.

I would have contacted you at, which the Internet RFCs say is the correct address for this kind of thing. But I can’t. Why not? Well, because you don’t even read the email from that address. How do I know? Because I sent an e-mail to it and got the response:

<>: host[] said: 552 5.2.2 Over quota

You’re supposed to respond to e-mail at that address! You aren’t supposed to let the mailbox fill up until people get over quota messages.

I hold out little hope that you will fix either problem. If you do bother yourselves to sort either of these things out, let me know. In the meantime I’ll continue to tell our customers not to use your e-mail service.

Kind regards,

Alastair Houghton
Managing Director
