SMTP client issued a RCPT TO command to declare a recipient address for the current mail transaction. This step validates whether the server will accept delivery to the specified mailbox or relay target. In honeypot or exposed SMTP services, automated scanners and spam bots frequently use RCPT commands to test relay capability, enumerate valid recipients, or prepare bulk message delivery attempts.
