Django - Trouble Sending Email in Production with Different SMTP Settings
I'm deploying to production and I've looked through the documentation and I'm still confused about I've searched everywhere and can't find a clear answer..... I'm working on a project and hit a roadblock. I'm currently working with an scenario with sending emails in my Django application when deployed to production. Locally, I can successfully send emails using the default SMTP settings, but once I deploy the app, I get the following behavior: `smtplib.SMTPDataError: 554 5.7.1 <email@example.com>: Relay access denied`. I've configured the email settings in my `settings.py` like this: ```python EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.example.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = 'user@example.com' EMAIL_HOST_PASSWORD = 'my_secure_password' DEFAULT_FROM_EMAIL = 'from@example.com' ``` I've double-checked that the credentials and host information are correct. Locally, I'm using Gmail for testing, but in production, I have to switch to a different SMTP server. I've tried both TLS and SSL configurations and can’t figure out why it’s being denied. I've also verified that the email account has permissions enabled for SMTP access. Additionally, I tried to send a test email using Django's shell with the command: ```python from django.core.mail import send_mail send_mail('Subject', 'Message', 'from@example.com', ['to@example.com']) ``` This results in the same relay access denied behavior. Is there any specific configuration or debugging step I should take to resolve this scenario? Any insights on common pitfalls or additional settings to check would be greatly appreciated! My development environment is macOS. Has anyone else encountered this? My development environment is Ubuntu. Has anyone else encountered this? I'm coming from a different tech stack and learning Python. Any pointers in the right direction?
