@No6671, great of you to come forward!
@Corjan-Meijerink, I can't see any blacklist for here.com on mxtoolbox.com. If they block it, they probably do it on purpose. Are there specific subdomains being used that can be checked? Probably also some exotic ports are use too. VPNs ar known for not translating undefined ports.
