Postfix sending messages but error in delivery
We have postfix mta in our office to send e-mails to multiple recipients but we send individual messages via our hosting provider. In this respect, hosting provider made below setup in their system;
mx0 = mail2.domain.com.tr (hosting provider)
mx30 = mail.domain.com.tr (office static IP and rDNS)
Now, when we send emails from office and when the recipient replies back to this message, they get below error
his message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
SMTP error from remote mail server after RCPT TO:<firstname.lastname@example.org>:
host mail.domain.com.tr [xx.xxx.xxx.x]: 554 5.7.1 <email@example.com>:
Relay access denied
When I checked wger.kernel.org output, below seen ;
250 2.1.0 Ok
Fine, it accepts NULL return-path as is mandated by RFC 2821 section 6.1
250 2.0.0 Ok
250 2.1.0 Ok
554 5.7.1 <firstname.lastname@example.org>: Relay access denied
