I will consider the contact method by email in the future.
Your support agent requested the full email headers of the returned message. I suspect that this is what triggered the cloudflare block. I suppose if I had known that this was the cause why I would have included them as an attachment in pdf or txt format.
From my perspective, the important outgoing emails were rejected, while my responses to the assistance through the ticket system were blocked. Not to mention that I was not receiving an answer in your own forum. The support email address is not very visible from the ticket sales site.
