I work with VeriSign and we’re doing some Q&A with a new product of ours that deals with anti-spam. I’m using my domain for testing and changed the MX record to mail.emailsecurity.verisign.com and I set the inbound SMTP server info on VeriSign’s end to mail.alaive.com. When I
try to send an email to email@example.com, it bounces immediately. Here is the header info:
Final-Recipient: rfc822; firstname.lastname@example.org
Diagnostic-Code: X-Postfix; host mail.alaive.com[18.104.22.168] said: 554
email@example.com: Relay access denied (in reply to RCPT TO command)
Can you tell me what’s going on here and on which end it is failing?
