It was discovered that Postfix did not flush the received SMTP
commands buffer after switching to TLS encryption for an SMTP session.
A man-in-the-middle attacker could use this flaw to inject SMTP
commands into a victim's session during the plain text phase. This

encryption is enabled, possibly allowing the attacker to steal the
victim's mail or authentication credentials. (CVE-2011-0411)
