328 To enable this, set `nnmail-split-methods' to `nnmail-split-fancy'.
|

|

330 The format is this variable is SPLIT, where SPLIT can be one of
|
|
|
331 the following:
|
|
|
332
|
|
16
|
333 GROUP: Mail will be stored in GROUP (a string).
|
|
0
|
334
|
|
|
335 \(FIELD VALUE SPLIT): If the message field FIELD (a regexp) contains
|
|
|
336 VALUE (a regexp), store the messages as specified by SPLIT.
|
|
|
337
|
|
|
338 \(| SPLIT...): Process each SPLIT expression until one of them matches.
|
|
|
339 A SPLIT expression is said to match if it will cause the mail
|
|
|
340 message to be stored in one or more groups.
|
|
|
341
|
|
|
342 \(& SPLIT...): Process each SPLIT expression.
|
|
|
343
|
|
16
|
344 \(: FUNCTION optional args): Call FUNCTION with the optional args, in
|
|
|
345 the buffer containing the message headers. The return value FUNCTION
|
|
|
346 should be a split, which is then recursively processed.
|
|
|
347
|
|
0
|
348 FIELD must match a complete field name. VALUE must match a complete
|
|
|
349 word according to the `nnmail-split-fancy-syntax-table' syntax table.
|
|
|
350 You can use .* in the regexps to match partial field names or words.
|
|
|
351
|
|
|
352 FIELD and VALUE can also be lisp symbols, in that case they are expanded
|
|
|
353 as specified in `nnmail-split-abbrev-alist'.
|
|
|
354
|
|
16
|
355 GROUP can contain \\& and \\N which will substitute from matching
|
|
|
356 \\(\\) patterns in the previous VALUE.
