Thank you, but the only issue is from Sophos. We send from the same
infrastructure since 10+ years and there are no issues on the above
websites (we have a reputable history for our IPs/domains, we are not
aware of any malware issues in years).
I'm pretty sure this is a false positive from Sophos (maybe related to
a new CNAME, so a new host it doesn't know and some heuristic on the
hostname), so I wanted to know if anyone have experience with the
specific "Time of click" filter from Sophos (we don't have general
issues on our url reputations, only this Sophos weirdness on a
specific url, as far as I have been reported).

Stefano
