About MailCheck: SMTP Test & Debug
MailCheck is the ultimate SMTP diagnostic tool designed for system administrators, developers, and IT professionals.
Stop guessing why your emails aren't sending. MailCheck gives you a direct look into the server conversation, helping you debug connectivity issues, verify SSL/TLS configurations, and test authentication credentials in seconds.
KEY FEATURES:
• Real-time SMTP Testing: Connect to any SMTP server (Gmail, Outlook, Office365, or custom servers) and verify connectivity instantly.
• Raw Server Logs: View the full verbose transcript of the client-server handshake. See exactly where the error occurs (e.g., 535 Authentication Failed, Timeout, or Certificate errors).
• Smart Port Configuration: Automatically toggles between SSL/TLS (465), STARTTLS (587), and Plain Text (25) based on your port selection.
• Security First: Verify if your server supports modern encryption standards.
• Privacy Focused: Passwords are NOT stored. All credentials are held in volatile memory (RAM) only during the session and are wiped immediately upon app termination.
PERFECT FOR:
- Testing new mail server setups.
- Debugging firewall or port blocking issues.
- Verifying "App Passwords" for third-party services.
- IT Admins troubleshooting client email configurations.
MailCheck is ad-free, lightweight, and built for speed.
[Note: This app is a diagnostic client and does not provide an email inbox service.]
