The Internet Mail format officially starting with RFC 822 selected the

Why?
Any interesting computer network seeks interoperability among
heterogeneous systems. All sorts of differences need to be dealt with,
including differences in the end-of-line construct.
The simplest and most scalable way to accomodate such differences is to
define a /single/ standard and require each system to between their
local convention and the network's canonical convention.
This approach was as the core or the early Arpanet protocols, including
FTP as already noted in this thread. That's from the early 1970s
timeframe.
RFC 822's predecessor, RFC 733, was 1977. SMTP was 1982. They merely
continued the convention.
Telnet and FTP chose CRLF as the end of line construct.
