Mails to Hotmail are all blocked

MartinGM — Tue, 23 Aug 2022 20:33:03 GMT

As of today, any email I send to a Hotmail address is blocked if sent through my broadband or mobile phone (both EE). This is a BIG problem for me 😞
I can send at a neighbour's house usinng a different ISP so it is EE, not my email address, that is the problem.
This is the message I get from Hotmail:

----- Transcript of session follows ----- ... while talking to hotmail-com.olc.protection.outlook.com.:

>>> MAIL From:<my email address> SIZE=1876

<<< 550 5.7.1 Unfortunately, messages from [209.17.115.50] 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 provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [DM6NAM12FT035.eop-nam12.prod.protection.outlook.com]

Any help gratefully received

Yes, it's not your email addy that's being blocked but your current public IP. It has been found to be on some blacklist of spammers etc.

All you can do is try & force it to change by rebooting your router a few times but not to often.

Thank you but I don't think that's the problem.
Because if I turn off my wifi and mail from my phone via 4G the mails still get blocked.

Hi @MartinGM

Thanks for coming here.

Can you try restarting the router and the device and try sending the email again?
