Summary
The issue at hand is email verification for users, which is not working as expected when deployed to Vercel, despite successful testing in Cursor CLI. The environment variables have been updated, and DNS records are in place, yet the verification emails are not being sent.
Root Cause
The root cause of this issue can be attributed to several factors, including:
- Incorrect configuration of email services
- Insufficient DNS record setup
- Environment variable mismatch between local and production environments
- Email service provider restrictions
Why This Happens in Real Systems
This issue occurs in real systems due to:
- Complexity of email verification workflows
- Variations in email service provider APIs
- Differences in local and production environment configurations
- Overlooked DNS record settings
Real-World Impact
The impact of this issue includes:
- Inability to verify user emails
- Increased support requests
- Decreased user trust
- Potential security vulnerabilities
Example or Code (if necessary and relevant)
import os
import smtplib
from email.message import EmailMessage
# Define email configuration
EMAIL_HOST = os.environ.get('EMAIL_HOST')
EMAIL_PORT = os.environ.get('EMAIL_PORT')
EMAIL_USERNAME = os.environ.get('EMAIL_USERNAME')
EMAIL_PASSWORD = os.environ.get('EMAIL_PASSWORD')
# Create email message
msg = EmailMessage()
msg.set_content('Verification email content')
# Send email using SMTP
with smtplib.SMTP(EMAIL_HOST, EMAIL_PORT) as smtp:
smtp.starttls()
smtp.login(EMAIL_USERNAME, EMAIL_PASSWORD)
smtp.send_message(msg)How Senior Engineers Fix It
Senior engineers fix this issue by:
- Double-checking email service configuration
- Verifying DNS record settings
- Ensuring environment variable consistency
- Testing email verification workflows thoroughly
- Implementing error handling and logging mechanisms
Why Juniors Miss It
Junior engineers may miss this issue due to:
- Lack of experience with email verification workflows
- Insufficient understanding of DNS record settings
- Overlooking environment variable differences
- Inadequate testing of email verification processes
