My IP address is on a number of blacklists (7 at last check) and I can't figure out how to find out why I'm on them. This has lead to emails to Microsoft email addresses bouncing.
Here is an example bounce:
I think my situation is slightly complex, as according to my web host,Reporting-MTA: dns; outmx-008.london.gridhost.co.uk
X-Postfix-Sender: rfc822; [my email address]

Diagnostic-Code: smtp; 550 5.7.1 Unfortunately, messages from [126.96.36.199]
weren't sent. Please contact your Internet service provider since part of
their network is on our block list (S3140). You can also refer your

My IP is 188.8.131.52, and I'm using Outlook and mobile (4g) broadband).[184.108.40.206] is outmx-008.london.gridhost.co.uk
This mail server is used when your personal IP address is blacklisted at least one time and you are using mail client like Outlook, Thunderbird etc.
My web host said I should get my ISP to get the address delisted or to change my IP, but they say they can't do it. I read the delisting FAQ and it said I should try to find out first why I have been blacklisted before manually requesting removal, but I'm not tech literate enough to find that out on my own...
Many thanks in advance.
[To the mods: I posted this same topic earlier but it was rejected as being 'off topic'. I don't think it is off topic, though in my haste I did neglect to include the bounce message or my IP. I noticed straight away but couldn't edit my message because it hadn't been approved. If for some reason this is still off topic, could you send me a message to explain why and point me to where I should post it instead?]
