countermail.com - Email Domain Verification & Deliverability Report

CounterMail is a privacy-focused email service based in Sweden, designed to provide maximum email security and anonymity. The service uses diskless servers, OpenPGP encryption, and operates its infrastructure through Swedish ISPs to protect user privacy. CounterMail caters to security-conscious individuals who prioritize encrypted communications and minimal data retention.

countermail.com implements SPF, DKIM, and DMARC authentication for outbound messages. As a privacy-focused provider, CounterMail emphasizes strong encryption and does not log IP addresses. The service supports OpenPGP for end-to-end encryption and uses RAM-only servers to minimize data persistence.

The countermail.com mail servers enforce strict recipient verification and reject messages to nonexistent addresses. The domain does not function as a catch-all. Due to the small scale and privacy focus of the service, inbound mail handling is straightforward, though senders should expect standard SMTP response codes for delivery confirmation.

For reliable delivery to countermail.com users, ensure your sending domain has valid SPF and DKIM records. Messages are subject to CounterMail's spam filtering before delivery. Note that CounterMail users may have PGP encryption enabled, so consider sending PGP-encrypted messages when possible for privacy-conscious recipients.
