To enable the fetchmail service to retrieve e-mails set the environment variable ENABLE_FETCHMAIL to 1. Your docker-compose.yml file should look like following snippet:

...
environment:
  - ENABLE_FETCHMAIL=1
  - FETCHMAIL_POLL=300
...

Generate a file called fetchmail.cf and place it in the config folder. Your docker-mailserver folder should look like this example:

├── config
│   ├── dovecot.cf
│   ├── fetchmail.cf
│   ├── postfix-accounts.cf
│   └── postfix-virtual.cf
├── docker-compose.yml
└── README.md

Configuration

A detailed description of the configuration options can be found in the online version of the manual page.

Example IMAP configuration

poll 'imap.example.com' proto imap
	user 'username'
	pass 'secret'
	is 'user1@domain.tld'
	ssl

Example POP3 configuration

poll 'pop3.example.com' proto pop3
	user 'username'
	pass 'secret'
	is 'user2@domain.tld'
	ssl

IMPORTANT: Don’t forget the last line: e. g. is 'user1@domain.tld'. After is you have to specify one email address from the configuration file config/postfix-accounts.cf.

More details how to configure fetchmail can be found in the fetchmail man page in the chapter “The run control file”.

Polling interval

By default the fetchmail service searches every 5 minutes for new mails on your external mail accounts. You can override this default value by changing the ENV variable FETCHMAIL_POLL.

  - FETCHMAIL_POLL=60

You must specify a numeric argument which is a polling interval in seconds. The example above polls every minute for new mails.

Debugging

To debug your fetchmail.cf configuration run this command:

./setup.sh debug fetchmail

For more informations about the configuration script setup.sh read the corresponding wiki page.

Here a sample output of ./setup.sh debug fetchmail:
