SMTP Credentials
Each project has unique SMTP credentials:
- Username: Automatically generated
- Password: Shown once at creation (can be regenerated)
- DSN: Connection string for frameworks that support it
You can regenerate your SMTP password at any time from the project settings. Remember to update your application configuration after regenerating.
Email Retention
Configure how long emails are stored:
| Plan | Retention |
|---|---|
| Free | 10 emails per project |
| Professional | Unlimited emails, 2 GB storage |
Private Asset Domains
For security, Mailcatcher doesn't load external images by default. You can whitelist trusted domains in your project settings to automatically load images from those sources.
