IMAP: Invalid TAG
This protocol anomaly triggers when it detects an invalid IMAP tag, i.e., a tag that begins with a white space, or contains non-alphanumeric characters. This can indicate a non-standard IMAP client or command line access to an IMAP server.
Extended Description
A protocol anomaly exists when an IMAP message contains an invalid tag. Receiving such a malformed IMAP message may indicate a non-standard IMAP client, or a command line access attempt to an IMAP server. The impact depends on how an IMAP server handles specially crafted messages.
