Emails sent to or from BigPond accounts, may be blocked if they contain links to blacklisted domains, or are using certain URL shorteners. The affected emails will be rejected and receive a bounceback message advising of this.
What are URL shortener?
URL shortening is a technique on the World Wide Web in which a uniform resource locator (URL) may be made substantially shorter in length and still direct to the required page.While URL shortening is desirable for legitimate business or personal reasons, because it can make long links aesthetically pleasing, allow you to track clicks or disguise an underlying address, it is open to abuse.For this reason, some URL shortening service providers have found themselves on spam blacklists, because of the use of their redirect services by sites trying to bypass those very same blacklists.Source |
Typically these domains are blacklisted by SpamHaus, which BigPond uses to assess mail for spam/malicious links.
Customers are advised to remove any links that may be responsible from the body of the email, this includes any links that may appear in the original email if you are replying or forwarding. Alternatively, you can test if there are any blocked links by sending a text-only email to see if it goes through.
As BigPond does not control listings in the SpamHaus DBL (Domain Block list), it is the responsibility of the domain owner to request delisting, and ensure their domains are not being exploited by spammers.
If the customer receives bouncebacks due to a certain domain, we recommend they contact the domain holder with the information.

How Can I Change My IP Address? |
It is recommended that you follow the above process to request that your IP address unblocked.
|
If restarting your modem allows you to briefly send an email or two before your emails are blocked again, there is a very good chance that you have a virus or trojan on your computer which is why your IP keeps getting blocked.
Entering your new IP address into the SpamHaus website will provide you with refreshed details, however they will probably be similar to those on your previous IP Address but with a newer timestamp.
PLEASE NOTE: If you experience the above, you may need to run more than a standard virus scan on all of your computers as these malicious programs are designed to be difficult to identify and remove.
SpamHaus will provide details on which trojan is causing the problems, when they last detected it active on that IP address.
Once you have done a full computer virus scan you may attempt to change your IP address, and confirm that it has changed with http://www.whatismyip.com/
The SpamHaus website also has FAQs which will answer a host of other scenarios which may be more applicable to your situation.
