Suddenly, I'm getting a new header generated by the server:
X-CMAE-Envelope: MS4wfGqMVuipltmeCPbiitdqBG891cCE7/P//vXDNOtCDJEfLg9lNhYFVSQ+skhOh0J1IvMFP/l595O+sNYbatKq/5b6L6AyZNxpUTVrbNC8OrJLjToAbs7S
FsyYlmJirfPTjogGa85QD3+iNXnEAg7vvNS53onrArzbrjMJv6s/+n4F2qOCf42z1PcdPIp9gRzuWA==
X-CMAE which is: "Cloudmark Authority Engine" and is an e-mail anti-spam.
I just recently added:
* fail2ban
* switch certificate from rapidSSL to LetsEncrypt
But did nothing related to spam... & I see no reference to CMAE, X-CMAE or Cloudmark in the wiki/forums.
Anybody knows something it?
Thanks
