Deferred: 450 4.1.8 invalid/host-not-in-DNS return address not allowed Message could not be delivered for 2 days Message will be deleted from queue I read that it might be because mail is coming from an IP address, not a DNS, but it looks like the DNS is shown so I doubt that's the issue.
Also, in /etc/postfix/main.cf, I saw this: Code: # INTERNET OR INTRANET # The relayhost parameter specifies the default host to send mail to # when no entry is matched in the optional transport(5) table. When # no relayhost is given, mail is routed directly to the destination. # # On an intranet, specify the organizational domain name. If your # internal DNS uses no MX records, specify the name of the intranet # gateway host instead. # # In the case of SMTP, specify a domain, host, host:port, [host]:port, # [address] or [address]:port; the form [host] turns off MX lookups. # # If you're connected via UUCP, see also the default_transport parameter. # #relayhost = $mydomain #relayhost = [gateway.my.domain] #relayhost = [mailserver.isp.tld] #relayhost = uucphost relayhost = smtp-server.columbus.rr.com I don't remember entering that host as my relayhost (though it is correct).
I think that it's a "message" from vasceria.com, saying that it can not find your MX. Have a look at your MX record and see if you can fix it.
Mail sends to other users though, just not that address. I was thinking it was return from his ISP. Also, I followed that link and yes, both of my name servers are from the same location. That's not something I'm too worried about. I don't know how I would be able to use a name server at a different location because I only have 1 IP address. In the DNS Manager, I select plastikracing.net as the domain and this is what shows for the MX records: Code: Mailserver Hostname server.vasceria.com www server.vasceria.com tristan server.vasceria.com forums
My error.. That is what I meant to say.. it's a "message" from the ISP who you are send that mail message to. I think that the reasoin is because of the MX reccord error.
