Re: DNS flushing is it OK?

Hi Jeremy,

It all looks ok from here. The DNSReport has come out ok.

The only thing that might be causing problems is your MX record, which is called

cimtechnologies.com

A receiving mailserver may see this as your server not having a hostname...

Does your DC/Exchange box have a hostname like DC.cimtechnologies.com? If so, that might be causing some Anti-Spam devices a problem as you will be sending mail from DC.cimtechnologies.com and when the receiving server checks this, it just gets cimtechnologies.com back from the DNS lookup...

No problems for helping out! Is what these forums are here for! (And some points wouldn't go amiss, i am only 13 points off 250!)

If you can get an NDR from one of the failures we can probably identify what is causing the problems

Re: DNS flushing is it OK?

jonathan,

Yup I agree to that! Congrats! I'll give to you the 13 points... I have a question about DC.cimtechnologies.com DC = domain controller ryt? what should i place there, if Im not wrong it is the netbios name of the server ryt???

what should i put in the FQDN? servername.cimtechnologies.com or mail.cimtechnologies.com?

What could be the right one? But one things for sure I've tried both of them and they are all valid FQDN... (Am I goin' nuts?!?!)

By the way here's my assigned points for you

Re: DNS flushing is it OK?

Your server should have a hostname of your choosing.

It can be anything you like, the FQDN then becomes [servername].cimtechnologies.com

The MX record that comes up for your domain has the FQDN of cimtechnologies.com, so the hostname is cimtechnologies.

What is the server called, the DNS name and NetBIOS name are usually the same. So if the server is called 'Server1' the NetBIOS name would be SERVER1 and the FQDN would be Server1.cimtechnologies.com

Re: DNS flushing is it OK?

Hi,

I did flushed the dns..and clear the cache but still to no avail. I've found out about SPF! we don't have SPF in our domain that's why maybe the REASON why we can't send mail to some domains (D*mn!)... Do you know how to set this up?!

Peace!
