Fetch e mails from external IMAP POP3

To enable fetchmail feature, set ENABLE_FETCHMAIL to true in your docker-compose.yml :

environment:
  - ENABLE_FETCHMAIL=true

Then add retrieval settings in postfixadmin like this :

You can change the fetchmail polling interval with FETCHMAIL_INTERVAL (in minutes) :

environment:
  - ENABLE_FETCHMAIL=true
  - FETCHMAIL_INTERVAL=5

A dedicated port (10025) is available with less restrictions for delivery. Use FETCHMAIL_EXTRA_OPTIONS with postfixadmin docker image for that purpose.

Example :

postfixadmin:
  environment:
    FETCHMAIL_EXTRA_OPTIONS="smtp localhost/10025"
