Yesterday I received an e-mail from someone asking a question about Nudge. I replied on the same day, as I always try to do. My e-mail bounced with the following helpful message:

Hi. This is the qmail-send program at

I’m afraid I wasn’t able to deliver your message to the following addresses.

This is a permanent error; I’ve given up. Sorry it didn’t work out.


Connected to but sender was rejected.

Remote host said: 550 5.7.1 mail from spam friendly countries with admins who overwhelmingly ignore or bounce complaints not welcome here

In the past, I’ve seen various concise wordings of the “550 5.7.1” message; usually something to the effect that my address was on some blacklist or another. A polite request to the provider’s postmaster address usually worked.

But from this one I gather that they’re now unconditionally rejecting all e-mails from Brazil. Isn’t that rather excessive…? Should I sue about restraint of trade, or whatever?

So if you’re a user of one of my products, and I don’t answer your e-mail, you may want to switch providers – or post here on the support boards. Sorry about that.
