Who do I contact at Telstra about having my IP address removed from a blacklist?

My IP address has been blacklisted by dnsbl.sorbs.netdul.dnsbl.sorbs.net and dnsbl.spfbl.net. I contacted SORBS support and received a reply that was very technical, but stated that my ISP can easily have my IP address delisted.

 

Telstra is my ISP, so who specifically can I contact at Telstra to have this done? 

 

This is the email I received from SORBS support: 

 

Hello,

 

This is not a SPAM listing.

 

The SORBS DUHL listing is used to list Dynamic IPs. Unfortunately a Dynamic IP cannot be removed from the DUHL list, since that is what the DUHL list is, a list of dynamic IPs. When the IP was listed, or why you are using the IP, has nothing to do with it.

 

If this address is actually static, the regional Internet registry contact for the address (your Internet service provider) should contact us with details of their statically and dynamically assigned ranges. Further to prevent relisting the reverse DNS names should be set to indicate static assignment.

 

Delisting is also possible by having the reverse DNS set to the same as the MX record for a domain. However, please be aware that the DNS PTR, MX and A records should have a minimum Time-to-Live of 12 hours.

 

What identifies the IP as dynamic, are the markers in the PTR. For example; key strings like dhcp, pool, dyn, cable, DSL, dial, cpe, cust, RES, IP address, etc.

 

QUESTIONS:

7.102.133.144.in-addr.arpa, type = PTR, class = IN

ANSWERS:

-> 7.102.133.144.in-addr.arpa

type = PTR, class = IN, dlen = 38

name = cpe-144-133-102-7.nsw.bigpond.net.au

ttl = 86400 (1 day)

 

------------

Name: cpe-144-133-102-7.nsw.bigpond.net.au

Address: 144.133.102.7

 

You may want to review our Dynamic IP FAQ at:

http://www.sorbs.net/delisting/dul.shtml

 

"The reverse DNS PTR record for the IP address involved needs to map back to the name given in the MX record, and to have a TTL of at least 43200 seconds

(12 hours)."

 

 

Your ISP should be able to help you with this change; it is easy for them to do. The IP will not be de-listed until this change is made.

 

If the ISP, cannot change the PTR to the MX record name, then adding the word "static" to the PTR would make the IP static; it could then be removed from the DUHL list. Note that it needs a TTL of at least 43200 seconds (12 hours).

 

 

Thank you,

Eric

send an email to postmaster@bigpond.com and include the following:

  • Exact dates and times of when you tried to send the email.
    Preferably in the following format (dd-mm-yyyy) (hh:mm AEST).
  • Sending domain/email address
  • IP address at the time of attempt
  • The exact Bounce back message/s
  • A copy from the message that you have tried to send (including any signature and attachments)
  • Your contact details

 

Its not a SORBS block message

I already did that days ago and have received no response and my IP address is still blacklisted. Who at Telstra can I contact about this problem?

You can contact bigpond tech support and they can raise an escalation, though they don't have a direct line to email engineering.

Easter public holidays would have caused delays

Hi Eric,

 

I work for Telstra and have 3 x static IP address which we've issued our customer and all three are blacklisted. I'm hoping you can assist me as this is a major issue for our Enterprise customer.

Please advise best contact method for this issue.


Thank you in advance for your support.


Warmest regards,
Joe
