Dovecot configuration for IMAP/POP3 and mail access.
Install Rspamd on Ubuntu 26.04, connect it to Postfix as a milter, configure Redis, and publish DKIM and DMARC records for your mail domain.
Postfix is an open-source mail transfer agent (MTA), a service used to send and receive emails. Dovecot is an IMAP/POP3 server and in our setup it will also handle local delivery and user authentication.
Set up PostfixAdmin on Ubuntu 26.04 with Nginx, PHP, MySQL, DNS records, and a Let's Encrypt certificate for a virtual mail server.
