I run a newsletter and whenever I send out emails to my subscribers I am getting "Too many connections from your host." errors from TPG owned email domains (eg @adam.com.au, @@iinet.com.au,@@aapt.net.au, @westnet.com.au etc). This does not affect all emails to those domains - about 60% are delivered and 40% fail. I am only sending out 10,000 emails at a time (which includes other domains like gmail.com, optusnet, bigpond etc).
I contacted my email delivery company, and they said that I may need to send the emails to the TPG domains at a different rate. They asked that I find out these values from TPG:
Is Tech support able to supply these values?

Please send me a PM with your TPG username or customer ID number to assist you accordingly.
Thanks for your reply. I am not a TPG User - I am trying to *send* emails to TPG users. As well as posting my question here I have also asked TPG Tech support, and was (after 3 chats) told to send my question to firstname.lastname@example.org which is reasonable since it is an email deliverability question. However, I have not had a reply so if you could help that would be much appreciated.
My question is:
What values does TPG want email senders to use for these parameters?:
