This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.
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
:
