Question

which protocol is used by client programs to send email to other servers
​

Answer 1

Answer:

Simple Mail transfer protocol

Answer 2

Answer:

SMTP

Explanation:

• Between email clients and servers, email is sent and received via the Simple Mail Transfer Protocol (SMTP).
• Email attachments and messages are transferred using the SMTP protocol. Email is sent between email servers and from email clients (like Microsoft Outlook) to email servers via SMTP (such as Microsoft Exchange). The majority of email clients, however, fetch email from the server via POP3 or IMAP instead. On the same physical server system, these two server programmes (SMTP and POP or IMAP) may coexist.
• The real data transport services are provided by the TCP/IP suite's underlying layers, which are used by SMTP, which works at the application layer.
