Hi everyone,
I've been having some mail sending issues with some messages going missing between sender and receiver. Investigating causes whilst setting up SPF/DMARC and looking at DKIM seems to show that avasout07.plus.net is on the SORBS spam list.
http://www.sorbs.net/lookup.shtml?84.93.230.235
This was tested using a free service at https://mxtoolbox.com/deliverability where you send it an email, and then the deliverability report comes back with possible issues.
It also shows up using a dedicated blacklist checker: https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3aavasout07.plus.net
What's the best way to get this to the right technical team at plusnet to follow up and get unlisted? Or to get my email routed via a different mail relay?
My MUA is setup to use an MTA at home. That MTA relays everything through relay.plus.net:587.
avasout07.plus.net appears to be (consistently) the server that forwards on my mail, and as it is on a spam database, it is fairly likely this is contributing to some of my emails going missing. I've noticed this most with recipients using hotmail.
Cheers,
Mark
