In IT, Short Message Peer-to-Peer (SMPP) is a type of protocol that allows for the transmission of a significant volume of SMS text messages. Typically, SMS text messages go through an SMPP, which can be used to connect external systems to a message center handling high SMS volumes.
SMTP(Simple Mail Transfer Protocol) is the gold standard for passing email messages from one mail server to another. Every email service uses some variation of this protocol. Thereâs one more difference between SMTP and IMAP/POP3: unlike the latter two, it requires no authentication to function.
