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
...
Generate a file called fetchmail.cf and place it in the config folder. Your dockermail 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 with proto IMAP
user 'username' there with
password 'secret'
is 'user1@domain.tld'
here ssl
Example POP3 configuration
poll pop3.example.com with proto POP3
user 'username' there with
password 'secret'
is 'user2@domain.tld'
here options keep ssl
More details how to configure fetchmail can be found in the fetchmail man page.
Debugging
To debug your fetchmail.cf configuration run this command:
docker run --rm \
-v "$(pwd)/config:/tmp/docker-mailserver" \
-ti tvial/docker-mailserver:latest \
sh -c "cat /etc/fetchmailrc_general /tmp/docker-mailserver/fetchmail.cf > /etc/fetchmailrc; /etc/init.d/fetchmail debug-run"
By default the fetchmail service searches very 5 minutes for new mails on your external mail accounts.
