Hi guys,
I'm running into problems with sending mail on our mailserver. Some mails are sent and delivered without any problems (eg Gmail), while others are deferred with "Sender address rejected: Domain not found"
Here are the logs for a specific mail that was trying to be sent:
May 24 03:45:55 mail postfix/smtpd[11011]: NOQUEUE: reject: RCPT from r3a-acuria.mta.dotmailer.com[212.1.222.9]: 450 4.1.8 <bo-4S9X-9ES-9GP6D-C0JGE@info.canifa.com>: Sender address rejected: Domain not found; from=<bo-4S9X-9ES-9GP6D-C0JGE@info.canifa.com> to=<bachdt@canifa.com> proto=ESMTP helo=<r3a-acuria.mta.dotmailer.com>

on MTA:
[root@mail ~]# nslookup
> r3a-acuria.mta.dotmailer.com
Server: 127.0.0.1
Address: 127.0.0.1#53
Non-authoritative answer:
Name: r3a-acuria.mta.dotmailer.com
Address: 212.1.222.9
Does anyone else can help me fix it?
Thank for insight
