Mailhog is not working in Laravel 8.x + Sail

Question

I'm using Sail with Laravel 8.x
I set it up and it's working perfectly.
However, as said here in the Doc, I'm supposed to be able to access the MailHog web interface at: http://localhost:8025 since I configured my .env like this:

MAIL_HOST=mailhog
MAIL_PORT=1025
MAIL_ENCRYPTION=null

But http://localhost:8025 shows me This page isn’t working

Any help? Please!

Answer 2

This applies to Laravel 9.x + Sail as well.

Mailhog is not installed by default within the docker-compose file when using Sail, and there is no mention of enabling it within the official docs (which is one of many things wrong with the Laravel documentation, but...).

As hinted at by the accepted answer, you need to add the following to your docker-compose.yml file:

mailhog:
    image: 'mailhog/mailhog:latest'
    ports:
        - '${FORWARD_MAILHOG_PORT:-1025}:1025'
        - '${FORWARD_MAILHOG_DASHBOARD_PORT:-8025}:8025'
    networks:
        - sail

After restarting Sail, you can then access the Mailhog web interface at localhost:8025

Answer 3

Try replacing "localhost" try with "mailhog" https://docs.docker.com/compose/networking/

Answer 4

Don't forget to run this after adding Mailhog to docker-compose.yml
