i had some problem with my smtp server because of my PTR record
i create a new reverse zone and add a ptr record point to my mail.domain.com from my ip(38.100.214.200)
but when i check it from online tools, all of them except zoneedit.com say me that my server has no ptr record.
is this the proper forum to ask for help with a reverse DNS issue on my co-located server?
View 12 Replies View Relatedi have a dedicated server with 2 ips and i am planning to run a nameserver, mailserver and webserver on the same server. i heard that reverse dns is important. how do i do that?
My questions are...
1. will it work if i setup the reverse zone in my server? or should i ask my host to setup reverse ip for me?
2. Do i have to setup reverse entry to mailserver or domain or nameserver? which is important to have reverse ip.
I'm with a German (dedicated server) Provider and have the ability to personalize the Reverse DNS settings through their CP.
No US provider had allowed me this setting before, so I'm clueless about it. Whats Reverse DNS, what if I change the current setting to like - rdns.mydomain.com? Whats the use?
some clarification with regards to Reverse DNS.
An example ip: xx.xxx.xxx.xx is owned by A Company via a DC. The they have their name allocated to the netname and description when i look up their ip address.
I have my ip xx.xxx.xxx.xx this is me and it currently contains my DC's name throughout when i look it up as the description and netname...
Both are from the same DC however the other company has their name allocated to the ip address and i would like to do the same. Does this require Reverse DNS? It dosent involve domains surely does it?

View 12 Replies View RelatedWe recently decided to move all our DNS to a service called DNS Made Easy and also our sever box. We setup what they call Vanity DNS with ns0.domain.com and ns1.domain.com so our clients did not have to change their nameservers.
Our records for all domains are now setup and looks like they are beginning to propagate. Here's where the question is:
IP - 1.1.1.1 is for domain1
IP - 1.1.1.2 is for domain2, domain3 and domain4
IP - 1.1.1.3 is for domain5
All domains have MX records pointing to a either Google or Mailtrust.
what is the best way to setup Reverse DNS and PTR's for this setup and what should we ask our ISP to do for Reverse DNS in this case.
if I do a reverse lookup on my server's IP it returns a host assigned by the data center. So is this something I should even be managing too or is that always left up to the DC? I run my own DNS for the forward lookup zones.
Also just a technical question, when you do a reverse lookup, how does it know where to look to get the host? I'm not sure I fully understand how these work.
what are the techniques used to find out the domains pointing to a particular IP?
View 1 Replies View RelatedI am having trouble pinning down exactly what I am doing wrong with reverse DNS at HE.net on a /27 subnet.
Example host:
65.19.156.29
master1.ipcoast.net
It looks to me like HE.net has properly deligated the subnet:
# dig -x 65.19.156.29 @ns1.he.net.
;; AUTHORITY SECTION:
subnet0.156.19.65.in-addr.arpa. 86400 IN NS ns2.ipcoast.net.
subnet0.156.19.65.in-addr.arpa. 86400 IN NS ns1.ipcoast.net.
And I have the zone file on both of those servers. But still won't resolve from outside coming in.
I researched a few options and have come to this conclusion use Ultramonkey (LVS + HA Proxy) -> apache2 mod_php/ mod_python (serve php / python)
-> lighttpd (serve static files)
-> mongrel (ruby server)
I have a VPS with the hostname myhost.domain.com, with four IP addresses, one of which is assigned to a shared hosting account (using WHM/cPanel) at sub.domain.com.
For email delivery purposes (I'm sending e-commerce receipts (that MUST be delivered) from PHP apps running on sub.domain.com), do I need to set up reverse DNS entries that say their IP addresses belong to myhost.domain.com, or to sub.domain.com?
I am trying to do Reverse DNS and PTR of my server, but it the documentation from cpanel.I followed the Documentation till Editing the Reverse DNS Zone from here. URL... My Server has IPv4, the problem is the First and the Third Step, and in that result image shown on cpanel site, it has shown like 1 , 2 ,3 so Do i have to write their 123 in even in my cpanel or write the IP or reverse IP.

I have a mobile email application (for Zimbra) that is not compatible with HTTPS, only with HTTP.
Is it possible to configure a Reverse Proxy so I can bypass the SSL? Something like this:

I was able to configure a Reverse Proxy but when it comes to https, something does wrong! here is my vhost config:
Quote:
NameVirtualHost mail.domain.com:*
<VirtualHost *>
ServerName mail
ServerAlias mail.domain.com
ProxyPreserveHost On
ProxyVia full
SSLProxyEngine On
ProxyRequests On
<proxy *>

I have all mod_proxy modules (and its sub-mods) load. If this is possible to achieve, I think it's only a manner of configuration lamess.
Have someone configured anything like this before?

I don't want them to know in which provider i am....
As title suggests I'm looking to make sure my hosting is set up to respond with valid PTR information so my server generated emails aren't flagged as spam.
I have full SSH access to the machine at root level.
Running a CentOS machine but there are also other virtual hosts using a shared ip.
I have a client coming to me from another provider. Their biggest problem currently is that many emails either vanish or some get emails while others don't.
I did a check on DNS Reports and found that the domain is on a shared IP address (800+domains) whereas its mail server points to another IP address. Neither of the IP addresses appear blacklisted in any spam databases. The only possibility seems to be the IP address for the web site which does not have have a PTR record (reverse DNS record).
Could this be why the emails are disappearing? They have even configured SPF for the domain etc. I would like to avoid facing a similar situation when the client moves to me.
A few days ago, when installing TUX, I have mounted the virtual hosting directory to var/www/html/mywebsite.com (that's an empty directory I created in order for TUX to work) via:
mount --bind /home/virtual/site1/fst/var/www/html/ /var/www/html/mywebsite.com/
command.....
After figuring out that TUX has some problems I reverted everything but not this mount --bind command.. What is the reverse command for this, so everything will come back to the point which they were before?

Forward lookup DNS is working perfect, but reverse lookup is completely broken.

i read somewhere that genuine emails i send from my site are not properly received by yahoo, aol and they have placed my email to bulk folders. Is this because i havent created a reverse DNS entry in my server?
how actually to create a reverse dns to my site with cpanel?
The host is using a main IP. I can bind more IPs.
Shall I share same IP with host and web site or better sperate them for different IPs plus reverse IP for each of them.
