Describe the problem/error/question
When I am creating a new user, invite is not sent
What is the error message (if any)?
Mail command failed: 530 Authentication required
Information on your n8n setup
- n8n version:
- Database (default: SQLite): SQLite
- n8n EXECUTIONS_PROCESS setting (default: own, main): own
- Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
Env variables are set as follows:
N8N_EMAIL_MODE = smtp

Credentials are correct - I can send the e-mail via Bash/Openssl using the same data via the following script (sensitive variables are truncated):
# Create temporary file for the email
EMAIL_FILE=$(mktemp)
# Create a simple email message
cat > "$EMAIL_FILE" << EOF

if [[ $EXIT_CODE -eq 0 ]]; then

else

exit 1
