mails can't be sent - no reverse (PTR) detected
hey there , as I had the problem that I can't send mails with postfix to gmx and web.de with that error in the log :
Code:Sep 28 10:27:10 root postfix/smtp[18395]: 4AA2AA06DD: host mx-ha02.web.de[212.227.17.8] refused to talk to me: 421-web.de (mxweb105) Nemesis ESMTP Service not available 421 Requested action aborted: local error in processing Sep 28 10:27:11 root postfix/smtp[18395]: 4AA2AA06DD: to=<*****@web.de>, relay=mx-ha03.web.de[212.227.15.17]:25, delay=2.1, delays=0.05/0.01/2/0, dsn=4.0.0, status=deferred (host mx-ha03.web.de[212.227.15.17] refused to talk to me: 421-web.de (mxweb003) Nemesis ESMTP Service not available 421 Requested action aborted: local error in processing)
I contacted 1&1 , they told me the problem are the dns settings . at intoDNS I see this error :
Code:ERROR: No reverse DNS (PTR) entries. The problem MX records are: 148.228.251.178.in-addr.arpa -> no reverse (PTR) detected You should contact your ISP and ask him to add a PTR record for your ips
but what exactly have I to do now ? :/ thanks for help!

Your IP does not have RDNS set, ask your hosting provider to set it for you. And also add an SPF/TXT record for your domain, if it's not added already.

It looks like the remote email server rejected the email or not accepted. Did you try to contact them in any alternate ways?
What's the output of the below commands from your server.
telnet 212.227.15.17 25
telnet 212.227.17.8 25

But I can see that it points to "root.eurenikz.de", When I try to do the look ups for your IP at various places on the web, it takes a very long time to get a response back.
A lot of times the response is.
PHP Code:;; connection timed out; no servers could be reached

Don't forget once you make DNS changes it will take 24-48 hours for DNS propagation to complete. Meaning you won't see the changes take affect immediately.
rDNS is REVERSE DNS to 1.2.3.4 would be entered 4.3.2.1, but then again the format all depends on how your provider takes the input. Hence why you should be consulting with them, they should be able to complete this for you.█ WattaServer.com
