It is easy to mitigate the harm, *if and only if* the recipient who is causing this "collateral damage" is ready and willing to make exceptions for legitimate senders - no matter how small perecentage this might be - in the blocked networks. In other words: if you block some range at large, you should always be ready to make specific exceptions in the block. For me, the golden standard was set by the Russian "mail.ru" service. I don't know if they still operate this way, but a few years ago, if you sent mail to them and it was rejected (which happened to me), you got in the rejection message a link to a very simple web form that you needed to fill in, and in a few hours you were unblocked, without any hassle. It was my most positive experience with any mitigation procedure for rejected emails ever. If everyone did like this, you could block whoever you want, no problem at all. > With Google and MS running so many people's email, that last > condition is rather dubious.

As for this, I totally agree. -- Regards, Jaroslaw Rafa [email protected] -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
