833  the @code{encoding} @acronym{MML} tag (@pxref{MML Definition}).  
834    @code{qp-or-base64} has another effect.  It will fold long lines so that
835    MIME parts may not be broken by MTA.  So do @code{quoted-printable} and
836    @code{base64}.
837    
838    Note that it affects body encoding only when a part is a raw forwarded
839    message (which will be made by @code{gnus-summary-mail-forward} with the
840    arg 2 for example) or is neither the @samp{text/*} type nor the
841    @samp{message/*} type.  Even though in those cases, you can override
842    this setting on a per-message basis by using the @code{encoding}
843    @acronym{MML} tag (@pxref{MML Definition}).
