nnimap mail splitting and bodies

nnimap mail splitting and bodies

[Lars Magne Ingebrigtsen]

I just noticed that nnimap downloads the complete article bodies when
doing mail splitting.  Is that really necessary?

I think so---I do statistical splitting based on the email content
(headers and body).  

This could be configuration option...

At least it was in the old nnimap. `nnimap-split-download-body' set to
`nil' is very interesting in many situations.

spam.el sets nnimap-split-download-body-default to t when a statistical
backend is used (one that looks at the body).  Then
nnimap-split-download-body was OR-ed with
nnimap-split-download-body-default in past versions of nnimap.el.

I can take a look at implementing those but am waiting for Lars to yay
or neigh the general nnimap-split-download-body* concept in the new
nnimap.

Yay.  I think.  :-)

Should nnimap default to not downloading the bodies when doing mail
splitting, and then only be overridden by either a user setting, or a
binding from the statistical splitting stuff?

I would vote for this (I can't see why you would need the body unless
you, uhm, need it).

nnimap-split-download-body-default and nnimap-split-download-body should
both default to nil.  The user should be able to customize
nnimap-split-download-body while Gnus functions should set
nnimap-split-download-body-default.  And then nnimap.el should look at

(or nnimap-split-download-body-default nnimap-split-download-body)

I think that would work for everyone.

Yes.  But the latter variable doesn't seem to exist.  :-)

It was in nnimap.el before you redid it.  Note the typo in the choice
("deault") which IMHO indicates no one used it since no one complained
AFAIK.

(defcustom nnimap-split-download-body 'default
  "Whether to download entire articles during splitting.
This is generally not required, and will slow things down considerably.
You may need it if you want to use an advanced splitting function that
analyzes the body before splitting the article.
If this variable is nil, bodies will not be downloaded; if this
variable is the symbol `default' the default behavior is
used (which currently is nil, unless you use a statistical
spam.el test); if this variable is another non-nil value bodies
will be downloaded."
  :version "22.1"
  :group 'nnimap
  :type '(choice (const :tag "Let system decide" deault)
                 boolean))

LMI> Yup.

Are you OK with bringing the above defcustom back?  If so the other
change is trivial.

If nobody ever changed it to anything other than the default, then
perhaps it isn't needed?  And nnimap now could just do what nnimap then
defaulted to?

I think you're right.
