POP3: Request Error Syntax Error
This protocol anomaly triggers when it detects an unparsed POP command line or header line. This can indicate a non-standard e-mail client or server or a back-door/exploit attempt.
Extended Description
The impact depends on how a POP3 server handles malformed POP3 requests.
