IMAP server for debugging.

IMPORTANT: This image is ONLY for developing/debugging proposes

This docker image is based on https://github.com/tomav/docker-mailserver If you look for a docker image for production environment, then go here: https://hub.docker.com/r/tvial/docker-mailserver/

This image is even simpler than tvial docker image. Includes only Postfix (SMTP) and Dovecot (IMAP) servers with one catchall mailbox [email protected] for all emails. So, it's very useful for debugging. Optionally, you can define another normal mailbox.

Every email received via SMTP will be delivered locally to [email protected], so it's safe for testing a web application sending emails with a production list of emails.

Using your favorite email client you can connect via IMAP protocol to see emails like original recipient would received them

cp docker-compose.yml.dist docker-compose.yml

Edit docker-compose.yml for set these environment variables:

• MAILNAME: Mail domain (by default, localdomain.test)
• MAIL_ADDRESS: Normal user mailbox email address (optional)
• MAIL_PASS: Normal user mailbox password

docker-compose up

Configure your email client with these parameters and test it sending any email to any email address
