Simple Mail Transfer Protocol (SMTP) is the correct protocol that facilitates the sending of email messages from a workstation to a mail server. SMTP is designed specifically for email transmission and operates primarily as a push protocol, allowing users to send outgoing messages to their email server.

In contrast, File Transfer Protocol (FTP) is utilized for transferring files over a network, rather than for sending emails. Network News Transfer Protocol (NNTP) is specifically tailored for the distribution, inquiry, retrieval, and posting of Usenet articles, not standard email. Internet Control Message Protocol (ICMP) is used for sending diagnostic and control messages, such as those involved in determining reachability and network errors, and is not related to email communication.

Thus, SMTP is the dedicated protocol that makes email transmission feasible, establishing the fundamental infrastructure for sending messages from users to their mail servers.
