Good Morning,

Just installed Xeams in Spam Firewall Mode, I can used it without problem for outbound message. But for inbound message I have a problem all valid Emails entered in my Exchange server are rejected so I go the the log and it seem's that the validation is made BEFORE sending the mail to Exchange ?? Do I also have to enter all my domain Email in Xeams or I have a setup problem, here is what I saw in the LOG

85] S <-- 250-SIZE 20971520

2020-06-03 08:56:55,215 - [        85] S <-- 550 5.1.1 <ErasedRecipientName@datadis.com>... User unknown

I changed the Email name before @ in MAIL FROM: and RCPT TO: retain anonymity of the sender and recipient,the RCPT TO is a VALID EMail recipient in my Exchange server, but I don't see
 any communication to Exchange before the validation is made ?

Thank's for any help !
