Taiga basics

Im a newbie in Taiga.
My admin installed the Taiga on our test server and I’m currently exploring to add member in Project.
I sent an invitation to my colleague, but they unable to receive any invite.

Any advise for me to take a look?

Thanks in advance

Is it a Docker install?

Main thing to change is

EMAIL_BACKEND = "django.core.mail.backends.console.EmailBackend"

to

EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"

I found this in the README.md when I was looking for EMAIL_BACKEND in my taiga-docker directory

Email Settings

By default, emails will be printed in the standard output (EMAIL_BACKEND=console). If you have your own SMTP service, change it to EMAIL_BACKEND=smtp and configure the rest of these variables with the values supplied by your SMTP provider:

EMAIL_BACKEND=console  # use an SMTP server or display the emails in the console (either "smtp" or "console")
EMAIL_HOST=smtp.host.example.com  # SMTP server address
EMAIL_PORT=587   # default SMTP port
EMAIL_HOST_USER=user  # user to connect the SMTP server
EMAIL_HOST_PASSWORD=password  # SMTP user's password
EMAIL_DEFAULT_FROM=changeme@example.com  # email address for the automated emails

# EMAIL_USE_TLS/EMAIL_USE_SSL are mutually exclusive (only set one of those to True)
EMAIL_USE_TLS=True  # use TLS (secure) connection with the SMTP server
EMAIL_USE_SSL=False  # use implicit TLS (secure) connection with the SMTP server

Put those variables into a .env file and restart taiga.
