DNS Problems

[scottlpool2003]

I'm having problems with DNS.

I've looked around and found some people having similar issues, but to be honest I'm quite illiterate with Linux servers.

Mail is being rejected with error #5.3.0 "Remote host said: 544 mail server permanently rejected message (#5.3.0)

Having looked around, and running diagnostics on MXToolbox I find a couple of errors:

SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner

I'm not so sure what to check here, but further reading is suggesting I have the whole DNS/Hostname/Mail settings setup incorrectly.

I have 2 IP addresses for the server: 77.68.58.218 (this is my main IP and ns1) and 77.68.58.250 (ns2) both appear to be functioning correctly.

The hostname of the server is server77-68-58-218.live-servers.net (I think this may be wrong and somebody suggested I change this to server.domain.com, which I did and it knocked all websites hosted on the server offline)

Right, now down to my DNS template...

This is the exact default template for all domains:

<domain>. NS ns.<domain>.
<domain>. A <ip>
<domain>. AAAA <ipv6>
<domain>. MX (10) mail.<domain>.
<domain>. TXT v=spf1 +a +mx -all
<ip> / 24 PTR <domain>.
<ipv6> / 64 PTR <domain>.
ftp.<domain>. CNAME <domain>.
ipv4.<domain>. A <ip>
ipv6.<domain>. AAAA <ipv6>
mail.<domain>. A <ip>
mail.<domain>. AAAA <ipv6>
ns.<domain>. A <ip>
ns.<domain>. AAAA <ipv6>
webmail.<domain>. A <ip>
webmail.<domain>. AAAA <ipv6>

And under the domain having issues (selecttravelmedia.com) the template appears like this:

*.webmail.selecttravelmedia.com. CNAME selecttravelmedia.com.
77.68.58.218 / 24 PTR selecttravelmedia.com.
ftp.selecttravelmedia.com. CNAME selecttravelmedia.com.
ipv4.selecttravelmedia.com. A 77.68.58.218
mail.selecttravelmedia.com. A 77.68.58.218
mx1.selecttravelmedia.com. MX (0) mx1.
mx2.selecttravelmedia.com. MX (0) mx2.
ns.selecttravelmedia.com. A 77.68.58.218
ns1.bigsparkpublishing.co.uk.selecttravelmedia.com. A 77.68.58.218
ns2.bigsparkpublishing.co.uk.selecttravelmedia.com. A 77.68.58.250
selecttravelmedia.com. NS ns1.bigsparkpublishing.co.uk.
selecttravelmedia.com. NS ns2.bigsparkpublishing.co.uk.
selecttravelmedia.com. A 77.68.58.218
selecttravelmedia.com. MX (10) mail.selecttravelmedia.com.
selecttravelmedia.com. TXT v=spf1 +a +mx -all
webmail.selecttravelmedia.com. A 77.68.58.218
www.selecttravelmedia.com. CNAME selecttravelmedia.com.

Could anybody elaborate on what the problem could be? Is it something to do with the hostname or would "Warning - Reverse DNS does not match SMTP Banner" be causing mail to be rejected?

This is causing a few issues as this domain uses email marketing.

Thanks in advance for any help/suggestions.

Your DNS Zone Template:

<domain>. NS ns.<domain>.
<domain>. A <ip>
etc.

NS value is empty. Delete this record, and add two new NS records (you can refer here: i explained there how you add new entries):

http://forum.parallels.com/showthread.php?t=266421

Note: Ignore values ns3 and ns4.mydomain.com, it's just for his example. you would probably have something like ns1 and ns2.something or what ever you called your nameservers.

I've done this and it has now caused a new error...

The DNZ zone has been synced to all domains. All domains are working fine, but using MXToolBox I still have issues with the reverse DNS:

SMTP Reverse Banner Check OK - 77.68.58.218 resolves to selecttravelmedia.com
SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner Ignore
SMTP TLS OK - Supports TLS.
SMTP Connection Time 0 seconds - Good on Connection time
SMTP Open Relay OK - Not an open relay.
SMTP Transaction Time 0.780 seconds - Good on Transaction Time

Session Transcript:

That happens for all domains.

This error only happens for the 1 domain (selecttravelmedia.com):

Did you do reverse DNS for this new values?

 

[scottlpool2003]

I haven't a clue how to do it I've looked at quite a few threads but they are not explained in a way I understand.

 

[MislavO]

Reverse DNS is not really "Plesk thingy", you're doing that where your server is broughted (what are you saying there is my IP xyz.xy.zy.yz point to e.g. hostname of server). Contact support team where your server is, explain them what is your problem and that you want to do reverse DNS, they will know what to do.

Thanks for your help, I'll do what you suggested.
