Hi, my rua report was rejected at RCPT stage with:
SMTP error from remote mail server after RCPT TO:<aggrep.dm...@protect-sk.com>: 550 5.4.1 Recipient address rejected: Access denied. AS(201806281) [DB5EUR01FT030.eop-EUR01.prod.protection.outlook.com] I search the Internet, but i found multiple similar posts, but no clean description what is cause, as most of them talk about something in exchange, which i am not familiar with. Please, can someone explain me, what this rejection means? What is (can be) real reason? thanks -- Slavko http://slavino.sk
