Hello folks! I have a quick question. I have one sender that I can't get mail from:

Nov  6 14:42:04 myserver postfix/smtpd[2671]: connect from web-cus11.integritynet.com[204.14.161.242]
Nov  6 14:42:05 myserver postfix/smtpd[2671]: NOQUEUE: reject: RCPT from web-cus11.integritynet.com[204.14.161.242]: 450 4.1.8 <devdiyadmin@dev.diysecurityforum.com>: Sender address rejected: Domain not found; from=<devdiyadmin@dev.diysecurityforum.com> to=<myaddress@mydomain.com> proto=ESMTP helo=<web-cus11.integritynet.com>
Nov  6 14:42:05 myserver postfix/smtpd[2671]: disconnect from web-cus11.integritynet.com[204.14.161.242]

Is there some way to receive email from the above bypassing the check? I tried adding the ip to my 'HELO/EHLO Checks' white list in cluebringer, but it still does not work.

Any help would be appreciated!

Thanks,
-Jake

from=<devdiyadmin@dev.diysecurityforum.com>

- Does "dev.diysecurityforum.com" a solvable domain name via DNS query?
- You can try list its IP address (204.14.161.242) in your Postfix parameter "mynetworks =" as a trusted mail server.

Thanks for the response. The sub domain was not resolvable and adding the IP as a trusted mail server did not work. I removed the 'reject_unknown_sender_domain' in the 'smtpd_recipient_restrictions' to be able to get a mail message from this server and then added the restriction back in.

Thanks!
