The issue is called DMARC, and most certainly with a reject policy, which basically tells recipients to reject messages that doesn't quite appear to come from the originator. This is problematic for mailing lists, that kind of act as a middle man, and even moreso because rejections end up as bounces to the mailing list software, which will end up disabling the bouncing address. So in the end, it becomes a story of how users from one domain are capable of throw out everyone else that checks their DMARC policy. Last time we went through this, we ignored the problem, for reasons I cannot remember now. I'll have a closer look at what mailman can offer and get back to you. -- Richard Levitte levitte@xxxxxxxxxxx OpenSSL Project http://www.openssl.org/~levitte/ -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
