Hello Team,
I work at a Unified Email Management provider.
Some of our customers are having problems trying to send emails to bigpond.net.au addresses.
The errors we see are given below.
Connection refused due to exceed max concurrent connections. IB007
sender rejected. IB504
Is it possible that you could increase our connection limit since we send emails on behalf of tens of thousands of businesses.
Below are our IP ranges that we send emails from. Could you please get in touch to discuss this with more details privately.
103.13.69.0/24
124.47.150.0/24
124.47.189.0/24
180.189.28.0/24
Thanks.
Kind regards,
Malinda.
