Not receiving mail from any out side domain
Problem reported by ph - July 24, 2015 at 2:09 AM

Hi ,
 
We have  configured Smarter Mail trail version with MX Method under Domain setup.
From Domain to same Domain incoming and outgoing mails are working fine.
from our domain to other domain like gmail or yahoo outgoing mails are working if the Domain setup is in local.
Hence we are not going to use local option any more we have to use MX record method.
 
We have to add some Entry like A Record ( WebMail URL) , Mail Pointer ( MX Record ) , PTR ( Reverser DNS Record) and  SPF Record.
 
Note :- we are using Arkadix.com as a mail domain .
 
Please  Guide proper Setup and DNS Entries  which  belongs to above Domain Name.
 
 
Thanks and Regards

Several problems:
 
arkadix-com.mail.protection.outlook.com 10 This MX has no address, perhaps it is pointing to a CNAME? Run a DNSReport to find out!
 
This may be caused by the fact that one or more of your DNS [nameservers] are not responding with a name:
 
WARN
TCP allowed Not all nameservers responded to queries via TCP. This means that queries that require TCP connections will get inconsistent answers, which can cause delays or intermittent failures. The nameservers that failed TCP queries are:

No Name Provided | 207.46.163.143
WARN
Nameserver software version
One or more nameservers responded to version queries. This can be considered a breach of security. If a malicious person or program had access to a version-specific exploit for your DNS server, displaying the version info openly will make their attack much easier. This should be removed or obscured. The nameservers that responded to version queries are:

195.5.171.110 responded with "Microsoft DNS 6.1.7601 (1DB14556)"
195.5.171.111 responded with "Microsoft DNS 6.1.7601 (1DB14556)"
 
 
 
Therefore, we cannot determine the "A" or HOST RECORD for your MX server.
 
Remember, you cannot use CNAMES for mail servers, they are PROHIBITED.  All MX servers MUST point to an "A" or "HOST" record.

MAIL
Status Test Name Information
FAIL
All IP addresses public  
FAIL
Connect to mail server
 
Using other tools, we are able to see that the PUBLIC IP address for your mail server is: NULL - NOT FOUND
 
However, that does not properly map to an rDNS IP address,
 
WARN
Reverse DNS entries for MX servers One or more addresses referenced by MX records do not have a matching reverse DNS entry. This can cause problems for mail deliverability for these servers. Some mail platforms will not accept or will delay email coming from mismatched addresses. The addresses without matching reverse DNS entries are:

195.5.171.110 has arkadix-com.mail.protection.outlook.com. | (null) listed.
195.5.171.111 has arkadix-com.mail.protection.outlook.com. | (null) listed.
 
 
Summary:  Setting up and running an e-mail server requires a thorough knowledge of:

the Windows Server 2008 and/or Windows Server 2012 operating systems
IIS
DNS
and all of the new antispam and mail delivery rules and regulations which have been put into place during the last two years.
 
 
I would start by making certain your DNS responds properly.
 
Then check that you have a valid "A" or HOST record pointing the FULLY QUALIFIED DOMAIN NAME of your MAIL SERVER to the IP ADDRESS of your SMARTERMAIL SERVER - right now it appears to point to OUTLOOK.COM [HINT HINT!]
