Postmaster and Abuse problem.
Posted on 2008-11-10
When we run a DNS report at DNSStuff.com, we get the following errors that we want to fix:
"FAIL Acceptance of postmaster address ERROR: One or more of your mailservers does not accept mail to firstname.lastname@example.org. Mailservers are required (RFC822 6.3, RFC1123 5.2.7, and RFC2821 4.5.1) to accept mail to postmaster.
exchange.domain.com's postmaster response:<br /> >>> RCPT TO:<email@example.com><br /> <<< 554 Transaction Failed Unsigned DSN for [spoofed?] message not originating here. <br />"
"WARN Acceptance of abuse address WARNING: One or more of your mailservers does not accept mail to firstname.lastname@example.org. Mailservers are expected by RFC2142 to accept mail to abuse.
exchange.domain.com's abuse response:<br /> >>> RCPT TO:<email@example.com><br /> <<< 503 Command sequence error: rcptto <br /> "
Both Postmaster and Abuse are setup and receiving emails. What are we missing?
