Cannot send email - error message: Blacklisted IP address

A few weeks ago I stopped being able to send email. It gets stuck in the Outbox and then shows this error message:
Sending' reported error (0x800CCC67): 'The server responded: 421 csmtp.tb.ukmail.iss.as9143.net csmtp Sorry your IP 126.96.36.199 is active in our local abuse blacklist. Contact Virgin Media abusedesk for delisting requests'
Other useful information:
I use Windows Livemail from my PC running Win10.
The same problem is there when I use my laptop
I have used the same account, ISP, and email for many years without a hitch.
I can receive email no problem; the issue is sending email
I cannot send email from my iPhone or Android phone when connected to home WIFI but I can send email if I disconnect from WIFI and use 4G
I can send email if I login to virgin webmail
I have done a full virus scan on my PC (all clear)
I have reset my password for the account.
It seems to me my IP address has been recently added to a blacklist. As I understand it I need my ISP (Virgin Media) to help me resolve that i.e. find out which RBL (blacklist) is causing the issue and help me become delisted (or reassign me a new dynamic IP address).
If anybody can help it would be much appreciated. I've spent many hours trying to resolve this issue but have not been able to solve it.
