No, because you send the NDR to a adress, which was detected by SPF as NOT being the source of the message. So you reach the wrong person. So instead you should just send nothing, if you filter based on SPF, because the whole point in spf is, when you filter it, you do it because you do not know the source (and the pretended source-adress is wrong)

then somebody else will provide free binaries.

do not use them. they are making money with unblocking. so potential clients are not reachable, just because spamhaus blocked them and they do not even know it (or do not see the point in paying for the spamhaus blackmailing)

you say it: best practice.
This means, there are other practices (for a reason). They might not be the best, but in some cases they are needed. strict SPF filtering breaks them.

you are destroying the sense of SPF.

consider someone spams you from a faked domain (the thing spf should prevent). Then you send backscatter-spam to the real domain.

fail.

If you have correct SPF, you will most likely get more spam. Why? Someone spams mailservers with your domainname, then it bounces because of failed SPF, and many mailservers are configured wrong, so you will get backscatter spam.

The irony of this is, that SPF says "it wasn't me" and the wrong configured mailservers then send YOU an answer saying "hey, we're not accepting your mail, because your SPF says it is not your mail".

the copies ARE worth something, because you want to play.
But this just means, you cannot sell more copies than are needed for the players. If one stops playing and another one starts playing, they can trade the license.

so its the best for both: seller and buyer. So ... resell more digital goods.

a game is nothing you consume. Its like a book. you read/play it once, then you sell it to the next person for a cheaper price.

thats the problem, the article addresses.

and when i bought it? Doesn't i have a right to reinstall it to new devices, independed from the author removing it from the store (for new sales)?!

but debian testing has freezes. Will Ubuntu-Rolling have Freezes half a year before a new LTS?

you have a gui on the client. its called xterm, or if you like a better terminal urxvt.

LMDE is a rolling release, too.

but it will only be as stable as a normal release now.
