Resolved 554 invalid DNS PTR resource record

[maniot]

I recently setup a server for a webshop with prestashop. The problem i have i cannot send email from the server, when i look into /var/spool/mail i see a lot of error like this:

----- The following addresses had permanent fatal errors -----
<[email protected]>
(reason: 554-kundenserver.de (mxeue006) Nemesis ESMTP Service not available)

----- Transcript of session follows -----
... while talking to mx01.1and1.fr.:
<<< 554-kundenserver.de (mxeue103) Nemesis ESMTP Service not available
<<< 554-No SMTP service
<<< 554 invalid DNS PTR resource record, IP=217.160.2.150
... while talking to mx00.1and1.fr.:
<<< 554-kundenserver.de (mxeue006) Nemesis ESMTP Service not available
<<< 554-No SMTP service
<<< 554 invalid DNS PTR resource record, IP=217.160.2.150
554 5.0.0 Service unavailable

I'm using the dns server of my hosting provider.
As i have no clue as where to change things to resolve the error i'm asking if someone would give me a clue.

It is the responsibility of your hosting provider to set up a PTR record for IP addresses it assign to you.

Your IP seems to be in a range assigned to 1&1 Internet AG:

inetnum: 217.160.2.0 - 217.160.2.255
netname: SCHLUND-CUSTOMERS
descr: 1&1 Internet AG
country: FR
admin-c: IPAD-RIPE
tech-c: IPOP-RIPE
remarks: INFRA-AW
remarks: in case of abuse or spam, please mailto: [email protected]

You must ask them to set it up. In case you're hosting several domains from the same IP address, my advice is to ask them to set it up as a PTR to an host inside a domain you own (e.g. myhost01.mydomain.net).

Some hosting provider do not create PTR records pointing to customers domains, but in any case, and as a bare minimum, they should have a PTR pointing to an host name inside one of their domains (e.g.: customer-xyz.1and1.com, or 217-160-2-150.1and1.com)

Agreed Sergio, they should set it after a request, but 1&1 (and some others) you can set it yourself too...

Hope that helps
Kind regards

Yeap, @Lloyd_mcse, that seems to be the case for 1&1 and best answer for this case!

Others may do different things as well, like e.g. on DigitalOcean, where I have my VPSs, and the PTR is automatically attributed when you set your VPS hostname.

Thanks a lot Lloyd_mcse and Sergio, problem solved. Indeed it is possible to add the PTR record with 1&1. With my other vps's it was attributed automatically.

best regards,
