Hi, We have a client that sends a lot of email to bigpond.com<http://bigpond.com/> domains. Roughly between 15k and 30k a day. I say a lot despite those numbers being fairly small, because no other client sends anywhere near this number on the platform to them.
The problem is they constantly get delivery problems as bigpond.com<http://bigpond.com/> are always deferring them for too many messages or too many sessions. I tried tweaking all kinds of delivery for the domains, max connections, max per connection, max per minute etc. The delivery seems to switch between two states, either 100 emails per hour, or roughly 2k per hour. But I see this state changing all the time despite the customer consistently sending their 15-30k volume. And yes I do see times where the client only sends the lower 15k a day getting the 100 per hour limits. Its not simply they get 100 per hour limited when sending more email. I tried contacting the postmaster@ and abuse@ but have not had a reply in over a month so not sure if I did something wrong or they aren't monitored. I wanted to reach out here to see if anyone at bigpond.com<http://bigpond.com/> could help look at this for us. Happy to provide specific details off list. Thanks, Dan
