Setting up an email server on Ubuntu involves several steps, including:
Installing Postfix: Postfix is a popular mail transfer agent (MTA) that routes and delivers email. Configuring Dovecot: Dovecot is an IMAP and POP3 server that works well with Postfix to enable users to retrieve their emails. Securing with SSL/TLS: This involves installing a certificate to ensure that email communications are encrypted. Setting up Spam Filtering: Tools like SpamAssassin can help filter out unwanted emails.
