Reverse DNS Lookup Keeps Failing
 
I have been using DNSStuff's DNS Report tool and no matter what I try I continue to receive FAIL on 'Reverse DNS Lookup'.
No matter what I have tried the result is always 'no reverse DNS (PTR) entries'.

I look in at 'pri.152.169.72.in-addr.arpa' and it seems right?

Code:

$TTL        86400
@              IN      SOA    www.giganetwireless.com. hostmaster.giganetwireless.com. (
                                2007090803      ; serial, todays date + todays serial #
                                28800  ; Refresh
                                7200    ; Retry
                                604800  ; Expire
                                86400)  ; Minimum TTL
                        NS      www.giganetwireless.com.
                        NS      www.giganetwireless.com.
211      PTR    giganetwireless.com.
211      PTR    www.giganetwireless.com.
211      PTR    webmail.giganetwireless.com.
210      PTR    login.giganetwireless.com.
211      PTR    mail.giganetwireless.com.
211      PTR    mail.giganetwireless.com.giganetwireless.com.
211      PTR    darlenes-homes.com.
211      PTR    www.darlenes-homes.com.
211      PTR    highcountryhomesofanza.com.
211      PTR    www.highcountryhomesofanza.com.
211      PTR    mail.highcountryhomesofanza.com.

When running 'dig @72.169.152.211 any giganetwireless.com' an MX wouldn't show up until I added the record '211 PTR mail.giganetwireless.com.giganetwireless.com.'

I use DNSExit service and have added the MX, A for email...

Can someone help shed a little light on my errors?

Thank you

You will need to contact your ISP and ask if they can set the reverse DNS for you.

Thanks for the reply....



I was afraid of that:(
Presently using HughesNet Commercial VSAT terminals for backbone, asking HughesNet to provide customer service is a bit of a joke.

I'm waiting for Verizon to complete my Data lines being installed this month, I would opt to ask them to run RNDS records for me and just set my WISP clients email clients to utilize the server IP rather than the mail server name until that time.

Kinda sucks because Yahoo and I'm sure all others place those incoming emails into the 'Bulk' folder rather than the 'Inbox'.

Crap I'll be glad to get away from HughesNet, my WISP clients can't use VoIP efficiently nor can online traders depend on the final buy-price due to the 7-14 seconds of latency.


Thank you for your help

Hotmail is also like this.

Now these days its sometimes better to end up in the bulk folder than the real inbox as it's got less spam :p

I've got revers DNS setup on all my servers (and all other things needed to get email working like SPF records), but this was not enough for my domains to get out of the bulk folders of Yahoo and Hotmail.

For Hotmail I needed to get my domains on what Microsoft calls SenderID.
For Yahoo, I needed to contact the Yahoo admins who added my domains to a "white" list.

Really- how would I achieve this on my server locally?

I'm getting ready to place another server online so I can run my own name servers.

SPF SIDF
I found that SPF and SIDF are basically the same animal, I had a hell of time getting any MS servers to accept email from my server.
I utilized one templated SPF site to the next never having success as having had created a satisfactory SPF record.
Then I stumbled upon the MS SIDF template site, one run through and the format was accepted instantly and my clients could then send mail to and from MS email servers.
The MS webmaster stated that our IP is not on any blacklist, so generally most all domains are acceptable once a properly formatted SPF | SIDF record is present.

I did a little experimenting with the 'Subject' line when sending email to a Yahoo email account- I found that depending on the Subject content dictated your odds of being placed in the 'Bulk' box.

In example- if you used a Subject of: Hello...

It is 100% you will wind up in the Bulk

Otherwise- if a Subject of: Is this client authorized in the central control appliance?

Is placed in the Inbox.

I'm sure I can be entirely wrong here, but this is what I encountered while testing last night.


Thank you for you help, the email is functioning.
I just use the IP rather than the mail server name until my new data lines are installed by Verizon this week to replace 3 VSAT's trying to deliver 6MB's and failing miserably bad:mad:

Have a killer day :D

A reverse record for your IP address can only be setup by your provider that assigned the IP to you. You can not setup this record on your own server. Call your provider and tell them to setup the record for you.

Thank you Till...

OK I see how the RDNS goes now...
I am getting new data lines installed and have already asked that a Reverse DNS Record be created on Verizon's end.


Thanks again Till.
