Mail server IP addresses have been blacklisted by Bigpond URGENT

Hi there

 

We have the following 2 elastic static IP’s hosted in our AWS account which we use for sending email:

 

46.137.254.182

54.251.110.21

 

For some reason, these have all of a sudden been blacklisted by you and our clients are no longer receiving their emails. The IP addresses don't appear to be on any blacklist sites.

 

Can you please remove these from your blacklist?

 

Example error:

    xxxxxxx@bigpond.com

    host extmail.bigpond.com [203.36.172.106]

    SMTP error from remote mail server after initial connection:

    554 Connection refused .46.137.254.182 is blacklisted. Contact Telstra Security Operations IB102

 

relay=extmail.bigpond.com[203.36.137.234]:25, delay=151525, delays=151524/0.34/0.5/0, dsn=4.0.0, status=deferred (host extmail.bigpond.com[203.36.137.234] refused to talk to me: 554 Connection refused. 54.251.110.21 is blacklisted. Contact Telstra Security Operations IB102)

 

Thanks in advance.
