Topic: Sending email 4.1.2 Error

Hello!

When I try to send an e-mail to foreign domain, mail-client shows me the next message:
"4.1.2 <mailbox@domain.com>: Recipient address rejected: Domain not found."

Internal transport works fine (mail1@our.domain => mail2@our.domain delivers in seconds).

What should I check?

Do you have correct DNS setting on server? Please check /etc/resolv.conf and /var/spool/postfix/etc/resolv.conf.

Re: Sending email 4.1.2 Error

Thanks a lot! I've installed OS into the VM at home and transferred it to the other server. So the gateway/router/DNS IP has changed. /var/spool/postfix/etc/resolv.conf contained the wrong IP.
