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

How did you access these failure logs @pietrocolombo ? I'm having the opposite issue where it's Gmail rejecting my emails, but accessing the logs in docker doesn't show me anything like the SMTP error you've shared.

Did you generate the password for gmail? @jcreek
This is useful if you use a Gmail account for sending emails using the container

To see the idContainer:
docker ps
To access the logs do:
docker logs idContainer

Is your problem just sending to Gmail account or just not sending to anyone?

I "solved" by configuring the container for sending the mail with the Gmail server

I've actually fixed the issue - it was AWS blocking my emails 🤦

Thank you for your help anyway @pietrocolombo - much appreciated!

@jcreek hey josh, do you remember the AWS specific issue? Was it the outbound rules in your security group?

[jcreek]

@dushyant89 there's a form you'll need to fill in, it's AWS themselves blocking it, not something in your environment. See https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/ for full details :)
