SMTP server not able to send AF notifications email.

Hi All,


I have an AF solution which has many notifications configured.

When I test my Email devilry channel plugin configurations, and send a test mail to my email ID, it successfully sends the mail.

But when I try for some other email IDs or groups I get below error-


From Primary SMTP server: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.1 Unable to relay for "email ID name"


This is a new AF server on which I get this issue. We have another AF server and when I repeat the above from that server, the mail is sent successfully even though I have configured the same SMTP server name in the new server.


AF version is 2018R2 for the new one and 2017R2 in the older one.


Also I noted there was a difference in the extension of email IDs in success and failure cases. When email Ids are it sends correctly and when it is it doesn't but I am not sure if this is the reason and how resolve it.


I have very less knowledge on SMTP server and its behaviors. Can anyone please advise?
