Confusion About Postfix Logs

There is a lot of confusion around how to read and manage Postfix logs, these can include Dovecot or other Mail Transfer Apps.

You should be using the Automated Docker Compose installation of Postfix, Roundcube Webmail, Dovecot and Certbot that makes https certificates

Simplest Way to view Postfix Logs

To see the logs, after you login via ssh or AWS SSM enter one of the following:

docker logs postfix
docker logs roundcube
docker logs dovecot
docker logs certbot
docker logs nginx

These logs are limited to 50 GB each, so it wont fill your disk with Postfix logs.

Only Certbot keeps some logs outside of docker, these are in opt/postfix-containerized/docker-volumes/var/logs
