Abstract

Internet email protocols include SMTP [RFC5321], IMAP [RFC3501], and POP3 [RFC1939]. IMAP and POP3 are both message store access protocols used by message store user agents (MUAs) to manipulate email messages after delivery. [RFC4409] defines a "profile" of the SMTP service that is specifically used for message submission. MUAs are expected to submit messages to mail submission agents (MSAs) using this approach.
