trouble with sending emails

[TigenTigen]

Hello, not sure to write it here, but I can't solve the problem by myself, so... I used this docker image to run as single smtp server for web app via docker-compose. Compose configuration: smtp: image: namshi/smtp:latest networks: - nginx_ext_network environment: MAILNAME: 'mailer' restart: always ports: - "25:25" But then the web app require to send an email, smtp server tries to do it, but fails. I tried it multiple times. With different ports. With different emails. Nothing works. Can you help me? Maybe some problem with my configuration? Or maybe you've seen this before?

I have the same issue. My SMTP service in docker-compose.yml goes as follows:

  smtp:
    image: namshi/smtp
    restart: always
    ports:
      - '25:25'
    volumes:
      - ./:/web
    environment: 
      - KEY_PATH=/web/config/ssl_keys/privkey.pem
      - CERTIFICATE_PATH=/web/config/ssl_keys/fullchain.pem

with ./ also being used by Django and Celery. I'm trying to send email through Django, here's my settings.py:

EMAIL_HOST = 'smtp'
EMAIL_PORT = '25'
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = 'noreply@localhost'

I'm trying to send a password reset email through saving a PasswordResetForm (how it's done by a default implementation, had to make my own for reasons).

Someone help?

Could you please elaborate a bit more for us newbies? :-)
