You don't have to read any RFC for this. It's simply that you
either cache a message somehow, or you have to fetch it again.

In mailx, the temporary mail file (cf. initbox() in lex.c) is
used for caching. As mailx reads the mailbox (that's principally
the same for POP, IMAP, and local folders), it appends messages
or parts of messages to that file. The send() function (don't
let that name confuse you) can then be used to access the
messages, performing conversions such as MIME decoding or
S/MIME decryption according to its parameters.
