Well, I know at least of Germany and I think also in Switzerland you are responsible for the mails if you take them. And I wouldn't risk to drop mails if I would live in USA where you could be sued for many million dollars. > Typical scenarios where backscatter may result are: > > - you're running a mailing list server, accept the incoming mail, and then > try to deliver it to the list members There you know the legal recipient and do not need to accept mails to not existing accounts. > - you're running a forwarding mail server, e.g. you permit customers to > have their custom domainname's e-mail service hosted with you, and forward > their messages to Google, Microsoft, Apple, Yahoo accounts, or whatever This also works by doing recipient verifications while receiving. > - you're running a smarthost for other services, e.g. automated equipment > such as scanners, surveillance/web cameras, alarm systems, etc. > - you're running a smarthost for e.g. web servers That I would not tell incoming mails. As you might note, that falls under the last sentence in my mail before: >> Something different is outgoing mails you received locally _from_ >> your users. > While you appear to think that these services shouldn't exist, it would be > a very sad day for you when you no longer could participate in exim-users > due to them implementing the policy you want and claim is legally > compulsory. Well, I use exim for long time now and are mostly reading in this list. I also know that there are some very bad mail servers out there that are even running exim. However, it was asked by Konstantin how he could improve his setup relating to backscatter. With regard to legacy stuff, it /is/ important where you come from. And it /is/ a really delicate decision to delete mails you are not the recipient for. Maybe it is not in your jurisdiction.
