Quickly verify email server connectivity, TLS/SSL, and authentication. You can attempt an SMTP send, or just do a handshake/auth test for SMTP, POP3, and IMAP.
Security note:
For safety, use a TEMPORARY PASSWORD while testing. Passwords are not stored server-side, and you use this tool at your own risk!
Tip: If SMTP isn’t working, first verify your ports using the
Port Forward Tester.
