This RFC suggests a simple method for workstations to dynamically access mail from a mailbox server. The intent of the Post Office Protocol (POP) is to allow a user's workstation to access mail from a mailbox server. It is expected that mail will be posted from the workstation to the mailbox server via the Simple Mail Transfer Protocol (SMTP). This RFC specifies a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvement. The status of this protocol is experimental, and this protocol is dependent upon TCP.

For the definition of Status, see RFC 2026.

For the definition of Stream, see RFC 8729.
