When I logon to the website of the filter service, i have the option to "test delivery to your server" when I test to domain A it returns
The test message has been succesfully sent to addr...@domaina.com, through email server mail.domainA.com on port 25. When I do the test to domain B (keep in mind it is the same server and IP that is originating the test) it returns SMTP error from remote mail server after end of data: host example.domain.com [x.x.x.x]: 554 5.1.0 Sender denied I guess I can restart transport services or reboot , i'm just wondering why after a few months of using this configuration it just started displaying this behavior.

TIA JP
