Hi, i would like that postfix always sends DSN, when requested by client and mail got forwarded to next-hop / final destination.
Thats works on some recipients, but not on all. postfix always sends DSN on specific destinations (e.g. web.de) <b...@web.de>: delivery via mx-ha02.web.de[212.227.17.8]:25: 250 Requested mail action okay, completed: id=1N0YD0-1hUYlq3qCq-00wNxk But when mail is send to some other foreign postfix servers, the foreign mailserver sends DSN. How can we specifiy, that only "our" postfix server sends DSN. Reason is, we have custom bounce messages and would like to only present our users our custom DSN text. Thank you. Stefan
