6.21.2. Content-Type
The Content-Type: "text/plain" is the default type for any news
article, but the recommendations and limits on line lengths set out
in section 4.5 Ought to be observed.
The acceptability of other subtypes of Content-Type: "text" (such as
"text/html") is a matter of policy (see 1.1), and posters Ought Not
to use them unless established policy or custom in the particular
hierarchies or groups involved so allows. Moreover, even in those
cases, for the benefit of readers who see it only in its transmitted
form, the material SHOULD be "pretty-printed" (for example by
restricting its line length as above and by keeping sequences which
control its layout or style separate from the meaningful text).
In the same way, Content-Types requiring special processing for their
display, such as "application", "image", "audio", "video" and
"multipart/related" are discouraged except in groups specifically
intended (by policy or custom) to include them. Exceptionally, those
application types defined in [RFC 1847] and [RFC 3156] for use within
"multipart/signed" articles, and the type "application/pgp-keys" (or
other similar types containing digital certificates) may be used
freely.
Reading agents SHOULD NOT, unless explicitly configured otherwise,
act automatically on Application types which could change the state
of that agent (e.g. by writing or modifying files), except in the
case of those prescribed for use in control messages (7.2.1.2 and
7.2.4.1).
