Every ~horsie gets an email address at <username>@tilde.horse using their shell credentials — no separate signup needed. Our email server uses the following software:
- Postfix — sends and receives mail
- Dovecot — serves mail to your email client and uses mail_crypt for stored-message encryption
- SpamAssassin — filters spam; supports custom rules
- OpenDKIM — signs outgoing mail so it reaches major inboxes
- OpenDMARC — verifies incoming mail sender policies
There is no webmail, you must use your own client. Use the following settings when signing in.
- Username: your ~horse username
- Password: your ~horse password
- Incoming mail server: tilde.horse
- Outgoing mail server: tilde.horse
- IMAP port: 993
- POP port: 995
- SMTP port: 465
- TLS: Required
Use IMAP (port 993) if you access mail from multiple devices — it keeps mail on the server. POP3 downloads mail to your device and removes it from the server.
New mail stored on the server is encrypted at rest using Dovecot mail_crypt. This protects mailbox contents on disk and in backups; it does not replace TLS or end-to-end encryption for messages in transit.
To change your password, log into your shell with an SSH client and execute passwd.
