# Email Sending Fix Summary
## Problem Identified
The email service was failing with the error:
```
SMTP.send_message() got an unexpected keyword argument 'from_addr'
```
This occurred when trying to send emails through the notification service.
## Root Cause
The issue was in the `email_service.py` file where `aiosmtplib`'s `send_message()` method was being called with `from_addr` and `to_addrs` parameters:
```python
# OLD CODE (incorrect)
await server.send_message(message, from_addr=from_email, to_addrs=[to_email])
```
However, the `aiosmtplib` library's `send_message()` method doesn't accept these parameters. The `from_addr` and `to_addrs` should be specified in the MIME message headers, not as parameters to `send_message()`.
## Solution Implemented
### Fixed Email Sending Method
**File**: `services/notification/app/services/email_service.py`
```python
# NEW CODE (correct)
# Note: aiosmtplib send_message doesn't use from_addr/to_addrs parameters
# The From/To headers are already set in the MIME message
await server.send_message(message)
```
### How It Works
The email service already properly sets the From and To headers in the MIME message:
```python
# From email_service.py - message construction
message = MIMEMultipart('alternative')
message['Subject'] = subject
message['To'] = to_email
message['From'] = formataddr((sender_name, sender_email))
```
The `aiosmtplib.send_message()` method reads these headers from the MIME message automatically, so we don't need to pass them as separate parameters.
## Additional Improvements
### 1. Trusted Relay Support
Added `SMTP_REQUIRE_AUTH` configuration option to support Mailu and other trusted relay servers:
```python
# In config.py
SMTP_REQUIRE_AUTH: bool = os.getenv("SMTP_REQUIRE_AUTH", "false").lower() == "true"
```
### 2. Updated Authentication Logic
```python
# In email_service.py
if self.smtp_require_auth and self.smtp_user and self.smtp_password:
await server.login(self.smtp_user, self.smtp_password)
elif not self.smtp_require_auth:
logger.debug("Skipping SMTP authentication - trusted relay mode")
```
### 3. Enhanced Logging
Added informative logging to indicate when using trusted relay mode:
```
[info] Email service configured for trusted relay mode (no authentication)
[debug] Skipping SMTP authentication - trusted relay mode
```
## Configuration Examples
### For Mailu (Internal Communications)
```bash
export SMTP_HOST=mailu.bakery-ia.local
export SMTP_PORT=587
export SMTP_REQUIRE_AUTH=false # No authentication needed
export DEFAULT_FROM_EMAIL=noreply@bakeryforecast.es
```
### For External SMTP (SendGrid, Gmail, etc.)
```bash
export SMTP_HOST=smtp.sendgrid.net
export SMTP_PORT=587
export SMTP_USERNAME=apikey
export SMTP_PASSWORD=your_api_key
export SMTP_REQUIRE_AUTH=true # Explicit authentication
export DEFAULT_FROM_EMAIL=noreply@yourdomain.com
```
## Testing
Created comprehensive tests to verify:
- ✅ Email message construction is correct
- ✅ MIME headers are properly set
- ✅ aiosmtplib compatibility
- ✅ Both trusted relay and authenticated modes work
- ✅ Configuration is valid for both scenarios
## Files Modified
1. `services/notification/app/services/email_service.py` - Fixed send_message call
2. `services/notification/app/core/config.py` - Added SMTP_REQUIRE_AUTH
3. `services/notification/README.md` - Updated documentation
4. `services/notification/test_email_sending.py` - Added sending tests
5. `services/notification/test_email_config.py` - Added config tests
## Expected Behavior After Fix
### Successful Email Sending
```
[info] Email service configured for trusted relay mode (no authentication)
[debug] Skipping SMTP authentication - trusted relay mode
[info] Email sent successfully to=contact@bakewise.ai subject='[Ventas] Test Subject'
```
### Error Handling
If there are still issues, they will be properly logged with clear error messages:
```
[error] SMTP send failed error="connection refused"
[error] Failed to send email to=contact@bakewise.ai error="connection refused"
```
## Troubleshooting
### If Emails Still Don't Send
1. **Check SMTP Server Connectivity**:
```bash
telnet mailu.bakery-ia.local 587
```
2. **Verify Mailu Configuration**:
- Ensure `RELAYNETS` includes your Kubernetes subnet
- Check Mailu logs: `kubectl logs mailu-pod`
3. **Test with Simple SMTP Client**:
```python
import smtplib
from email.mime.text import MIMEText
msg = MIMEText('Test')
msg['Subject'] = 'Test'
msg['From'] = 'noreply@bakeryforecast.es'
msg['To'] = 'test@bakeryforecast.es'
with smtplib.SMTP('mailu.bakery-ia.local', 587) as server:
server.send_message(msg)
```
4. **Check Notification Service Logs**:
```bash
kubectl logs notification-service-pod | grep "Email"
```
## Summary
The email sending issue has been resolved by:
1. **Fixing the aiosmtplib usage** - Removed incorrect `from_addr` and `to_addrs` parameters
2. **Adding trusted relay support** - For Mailu and internal email servers
3. **Enhancing error handling** - Better logging and debugging information
4. **Maintaining compatibility** - Works with both internal and external SMTP servers
The notification service should now successfully send emails through Mailu without authentication for internal communications, and with proper authentication for external SMTP services.
