Since last week I am not able to forward certain emails as attachment.
I am getting this error message:
5.2.0 SMTP602 Message contains Spam Content ;id=f7MVmJfI9SgGFf7MVmfqa9;sid=f7MVmJfI9SgGF;mta=vie01a-pemc-psmtp-pe12;dt=2021-10-25T23:18:31+02:00;ipsrc=188.8.131.52;
error code: 17099
before last thursday I was able to forward these emails without any problem. I checked the emails before and after and nothing has changed in the emails.
I also tried to forward emails from the past that I had managed to forward in the past.. and it does not work anymore.
Has UPC cablecom updated something? do I need to make changes to the port I am using?
