Anti-spam approach	Not separately documented as a technical methodology beyond standard server-side mail filtering; the Privacy Statement discloses that email server logs (sender/recipient addresses, connecting IPs) are retained for 48 hours to prevent brute-force attacks and aid debugging, and specifies that message content is not read except for service operation, troubleshooting, or suspected Terms of Service violations.	Described by Posteo only as a 'highly efficient spam and virus filter' — no further technical methodology is publicly documented.
