Configuring IMAP

Now that you're able to get e-mail delivered, you can read e-mail from the local mail spool by using the mail command. In general, it is more useful to be able to retrieve your e-mail from off the box however, which typically means webmail, pop3 or IMAP. In this recipe, we're going to look at setting up a Dovecot e-mail server.

How to do it...

1. Install the dovecot-imap package:

   sudo apt-get install dovecot-imap
   

2. Configure the SSL cert and key:

   sed 's|^ssl_cert .*|ssl_cert = </path/to/cert|g' /etc/dovecot/conf.d/10-ssl.conf
   sed 's|^ssl_key .*|ssl_key = </path/to/key|g' /etc/dovecot/conf.d/10-ssl.conf
   

3. Configure the mail server to require TLS by editing /etc/dovecot/conf.d/10-master.conf and set port = 0 under inet_listener imap.
4. Restart ...
