Detail

StartTLS is a protocol command used to inform the email server that the email client wants to upgrade from an insecure connection to a secure one using TLS or SSL. StartTLS is used with SMTP and IMAP, while POP3 uses the slightly different command for encryption, STLS.


An attacker might use the disclosed information to harvest specific security vulnerabilities for the application identified.
