Steps to reproduce

After initializing and starting the project using the docker-compose file version 1.9.0, modifying the SMTP service address in the .env file, when the password contains unconventional characters such as ?~$, authentication cannot be completed regardless of whether single or double quotes are used. The issue was resolved after changing the password to purely letters and numbers.

✔️ Expected Behavior

Successfully authenticated and sent email
