Did you get any error message when sending the emails or its directly went through the 'Sent Folder'? If so, it means that the email was delivered. Do you still have the emails that were not received? If yes, we recommend to raise this directly to our postmaster (firstname.lastname@example.org )to check if this is an issue with the TPG E-mail or with the recipient's E-mail.
The email was sent to a bundle of recicpients on Thursday and only the Bigpond were rejected - with messages received today (Sunday).
The error message for all was
The reason for the problem: 5.4.7 - Delivery expired (message too old) 550-'5.7.1 Connection refused. 188.8.131.52 is blacklisted in Invaluement RBL List. See http://www.invalument.com/removal'
I did a Google search and have switched my outgoing mail server to use SSL (it did have no encryption) Port 465. Could this be the problem? I won't know for a few days if it has worked will I?
Send us a PM with your Username/Customer ID together with the affected E-mail address. We will raise this to our postmaster for investigation.

I have also had the problem sending to bigpond.com addresses this weekend.
The outgoing email is eventually returned with
Diagnostic-Code: smtp; 5.4.7 - Delivery expired (message too old) 550-'5.7.1 Connection refused. 184.108.40.206 is blacklisted in Invaluement RBL List. See http://www.invalument.com/removal' (delivery attempts: 0)
Actually, the URL should be http://www.invaluement.com/removal
When you put 220.127.116.11 into this website you get the response
18.104.22.168 is currently blacklisted on ivmSIP
I have also had the same issue sending individual or group emails to bigpond.com adresses. The recipients complained that they were not being delivered despite me recieving a delivery reciept. This has been worse over the recent long weekend in NSW.
In order to investigate this further, we need you to send us a PM answering the questions below.
