how to sort (filter) msg which contain MS word documents

how to sort (filter) msg which contain MS word documents

[Uwe Brauer]

Hello


I would like to sort my messages in a given group such that the
message which contain attachments of word documents are separated form
the rest. I know that for new message I could use the gnus-splitting
group and specify the 
content type like:
    ("Content-type" "application/msword" "DOC")

But what can I do for other groups?

thanks

Does this actually work?  I think that nnmail-split-methods only apply
to the headers...

Maybe...

You are right! So there is no way to split DOC attachments?

You need to widen the buffer during the splitting and search for
application/msword.  There's an example in (info "(gnus)Fancy Mail
Splitting") from where you can start:

,----[ (info "(gnus)Fancy Mail Splitting") ]
| `(: FUNCTION ARG1 ARG2 ...)'
|      If the split is a list, and the first element is `:', then the
|      second element will be called as a function with ARGS given as
|      arguments.  The function should return a SPLIT.
| 
|      For instance, the following function could be used to split based
|      on the body of the messages:
| 
|           (defun split-on-body ()
|             (save-excursion
|               (save-restriction
|                 (widen)
|                 (goto-char (point-min))
|                 (when (re-search-forward "Some.*string" nil t)
|                   "string.group"))))
| 
|      The buffer is narrowed to the header of the message in question
|      when FUNCTION is run.  That's why `(widen)' needs to be called
|      after `save-excursion' and `save-restriction' in the example
|      above.  Also note that with the nnimap backend, message bodies will
|      not be downloaded by default.  You need to set
|      `nnimap-split-download-body' to `t' to do that (*note Splitting in
|      IMAP::).

The problem is that I have to set nnimap-split-download-body to t, and
that will slow down the downloaded considerably which is slow enough.

I tried out,

(gnus-summary-limit-to-bodies "application/msword" nil)
in a given group and that seems to work ok.

If you have control over mail delivery (e.g. procmail) you can insert a
header in the message if there's a particular pattern within it, and
then split based on that header.

I wonder if IMAP has a way to check quickly if an article has a
particular attachment.  That would be nice too, just ask the server.

I have not!

How to find out?

UB> How to find out?

Look at the IMAP RFCs, which I found hard to understand.  Maybe Simon
can answer this with a yes/no and if yes, I can dig further.

Simon: "particular" means a particular type, we don't care about the
name (but it would be nice to get as much information as possible for
splitting rules, including name and size besides MIME type).

The sexp imapd returns on the FETCH BODY which nnimap issues when
opening the *Summary* buffer contains all of the MIME data for each
FETCHed article.

FETCH BODYSTRUCTURE is similar and may provide more data.

I don't see any way of searching for all articles which match a given
mime type.  You can SEARCH for any string, but there will, of course, be
false positives.  So I suppose you'd have to SEARCH for the mime type as
a string and use FETCH BODY calls to rule out the false positives.
