$2.99 · Designed for iPad

Instantly diagnose SMTP connection issues. View raw server logs, check ports, and verify SSL/TLS encryption. The essential tool for IT admins & developers. 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.]
