SMTP server did not accept the password - tried multiple smtp's

Installation Issues
Hey everyone,
I recently Installed passbolt community edition on my server and I’ve tried setting up SMTP with multiple providers including Gmail, Office365 and even my own mailcow smtp server to no avail, I keep getting the same error:" SMTP server did not accept the password. " going over the mailcow smtp logs here’s what I could find

here’s my current docker-compose config:
environment:
APP_FULL_BASE_URL: 'something something
DATASOURCES_DEFAULT_HOST: “db”
DATASOURCES_DEFAULT_USERNAME: “zzz”
DATASOURCES_DEFAULT_PASSWORD: “yyy”
DATASOURCES_DEFAULT_DATABASE: “xxx”
EMAIL_DEFAULT_FROM_NAME: “Passbolt”
EMAIL_DEFAULT_FROM: “xxx@xxx.com
EMAIL_TRANSPORT_DEFAULT_HOST: “localhost”
EMAIL_TRANSPORT_DEFAULT_PORT: 587
EMAIL_TRANSPORT_DEFAULT_USERNAME: “xxx@xxx.com
EMAIL_TRANSPORT_DEFAULT_PASSWORD: “something somethinf”
EMAIL_TRANSPORT_DEFAULT_TLS: true

what am I getting wrong ?
any help would be very appreciated.

Hello @idanzhavi09 , welcome to our community :wink:

I have tried to reproduce your setup using the environment variable and I am not able to reproduce the issues. From the logs you’ve shared it looks like mailcow shows no auth attempt which suggest that the auth process is not even starting.

This could be due to network issues, is your passbolt instance behind a firewall?
Could you ensure that the server is able to reach any of those SMTP server?
