At www.dnsreport.com I am getting this "Mail server host name in greeting" error on each domain on a new server:

designhosting.biz exclusive IP site
http://www.dnsreport.com/tools/dnsreport.ch?domain=designhosting.biz

WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.

mail.designhosting.biz claims to be host godslove.designhosting.biz [but that host is at 216.180.242.170 (may be cached), not 63.247.80.43].

designhosting.us check for a shared site.

===================================

I migrated from one server to another server with a different main IP and now these errors.

How would I fix this?
 
Hi,

godslove.designhosting.biz is the name of the server.

The main IP on this server is:
216.180.242.170

Are you saying my mail record does not match the reverse entry by this line?

Asking DNS2.GNAX.NET. for 43.80.247.63.in-addr.arpa PTR record: Reports designhosting.biz. [from 209.51.128.18]
 
Ok I just added the reverse dns for designhosting.biz but am still getting the "Mail server host name in greeting" warning at dnsreport.com

Thanks!
 
Qmail uses the primary ip of the server to send the email. Try changing the A record for mail.designhosting.biz to point to 216.180.242.170

mail.designhosting.biz. A 216.180.242.170
 
Hi,

Changing the mail record got rid of the "Mail server host name in greeting" error.

Each time I setup a new domain in Plesk it shows the mail record as the IP of the site it was setup on using the domain template.

The Plesk dns zone template for domains is:
<domain>. NS ns1.designhosting.biz.
<domain>. NS ns2.designhosting.biz.
<domain>. A <ip>
<domain>. MX (10) mail.<domain>.
ftp.<domain>. CNAME <domain>.
mail.<domain>. A <ip>
ns1.<domain>. A 63.247.80.42
ns2.<domain>. A 63.247.80.43
webmail.<domain>. A <ip>

Am I suppose to change the mail record IP in the template?

I tried adding godslove.<domain>. to the domain template and added a site and it still shows the "mail" record with the IP of the site.

Is there any other way to do this besides changing every domain's dns records?

Is this the reason the mail que in Plesk is backing up?

Thank you!
 
The server company added godslove.designhosting.biz to something ??? on their system and that removed the mail name error I believe.

My main server IP has an A record and a PTR record for the server "main IP and mail listing". Part of the reason this was so confusing before is that one of my nameservers was also the main IP of the old server. Plesk mail works from the server's main IP.

This is my server template now as you can see it does not have the ns1 and ns2 A records for customers on the server because these have been listed on my nameserver domain designhosting.biz along with the A record for godslove.designhosting.biz below:

216.180.242.170 / 24 PTR mail.<domain>.
<domain>. NS ns2.designhosting.biz.
<domain>. NS ns1.designhosting.biz.
<domain>. A <ip>
<domain>. MX (10) mail.<domain>.
<domain>. TXT v=spf1 a mx ~all
ftp.<domain>. CNAME <domain>.
mail.<domain>. A 216.180.242.170
webmail.<domain>. A <ip>
www.<domain>. CNAME <domain>.

Hope this helps you!
 
Hi, I am trying a similar configuration, but my datacenter does not know how to get this to work. Would it be possible to find out exactly what your provider did for this to work?

Your help is greatly appreciated.

I think I have the same problem and the above posts dont make much sense to me.

The bounced error I got was:

Spam Filtering System Msg: Your email address or your email service provider server has been identified as open relay or DNS unsafed. This email has not been delivered.
<jsv-smtpgw #5.1.1>

Anyone able to help ?

Is it something I can fix on my box - or is it something I need my ISP / Web host to do ?

DNS Report shows:

mail.sustainableit.com claims to be host angusserver1.com [but that host is at 64.72.127.159 (may be cached), not 64.72.127.253].
