Hi,Not sure why but my domain is in your blacklist and even empty email is bounced by uri.ire1.sophosxl.com.
Thank for the help.
Thanks for reaching out to the Sophos Community Forum.
Currently, the website is classified as "Shopping", though you can submit a request to recategorize the website using the following link. - https://support.sophos.com/support/s/filesubmission?language=en_US
You will need to select "Web Address (URL)" and then fill out the form.
Unfortunately, we still experience difficulties:"host mx-02-eu-central-1.prod.hydra.sophos.com[188.8.131.52] said: 554 5.7.1 Service unavailable; Sender address [email@example.com] blocked using uri.ire1.sophosxl.com (in reply to RCPT TO command)"
Are you using any Sophos Email protection on your environment, or are you trying to send emails to a site that uses Sophos' Email protection?
I've reached out to our team to inquire further, do let me know if you can clarify the above.Edit/Update: I was informed by our team that the domain is no longer being blocked. If you continue to experience issues, please let me know by replying below.
