SMTP error from remote mail server after initial connection: 554 5.7.0 Blocked

the configuration of the container is this:
mail:
image: bytemark/smtp
restart: always
networks:
- frontend
labels:
- "traefik.enable=false"

if I use an external server it works. But I would like to send the mails with my domain

Currently, the image support only amd64. I would love to see an arm architecture support build. ❤️
I want to run plausible on an arm64 architecture based server. But as this image only supports amd64 I am not able to do the same.

Help pls!

This is used in plausible analytics docker compose

version: "3.3"
services:
  mail:
    image: bytemark/smtp
    restart: always

it restarts with

exec /usr/local/bin/docker-entrypoint.sh: exec format error

I'm running the Basic SMTP server and trying to send an email using Python + SMTPLib but I always get "Connection refused" Do you have any examples on how to send an email with the Basic SMTP server?

The delivery is failing for me because of the hostname.

To what is the fully-qualified hostname set in a container?
Can it be set with MAILNAME?

Hi
I created a simple mail server with this command

docker run -d --name mailserver -p 25:25 bytemark/smtp

Then tried to send a message to my personal gmail account and got this error

How can i fix this ?

Hi, where I can verify sent emails? Where in the logs I can see that?

Currently hosting on a VM withing Google Cloud Platform that does not have ipv6 configured.

Is there a way to turn off ipv6 lookups so that it only uses ipv4?
