Yes of course I did, it's obvious. It's really annoying that your provider rejects emails with attachments (maybe there's an option in the settings?). I sent the message to the company that "respects" your privacy the most then.
I received your email, now!
It seems that the issue mainly comes from attached files. There is no option for this, unfortunately. On the other hand, it's an old email address I mainly use for my website, so it is quite exposed to spam nonetheless.
Thank you again for your review, I will put you on the hall of fame today.
