Cannot send email "Your email contains spam" / Blacklisted

[mythil]

So my email address with you: [REMOVED] started to pop up with an error that I cannot send emails out saying.

Message could not be sent to the following recipients: ["redacted@gmail.com" <redacted@gmail.com>] (421 - 421 4.2.0 SMTP608 Too many spam emails from your user [REMOVED]@VirginMedia.com in the last hour. Retry later. ;id=buotrIccd2RyUbuotrMWJH;sid=buotrIccd2RyU;mta=oxsmtp4-prd-nl1-vmo;d=20240219;t=045955[CET];ipsrc=100.107.83.37;
)

I couldn't find a single thing to help on the Virgin Media website. When I looked at other sources online it says the domain is blacklisted from sending emails.. 

Why? I only ever send emails to friends or companies I work with.. I haven't even sent an email in hours so that contradicts the error message..

Wait an hour before trying to send an email again. If the issue persist then consider following the advice here My Virgin media email has been hacked | Virgin Media Help
