344 | The format is this variable is SPLIT, where SPLIT can be one of | |
345 | the following: | |
346 | ||
347 | GROUP: Mail will be stored in GROUP (a string). | |
348 | ||
349 | \(FIELD VALUE SPLIT): If the message field FIELD (a regexp) contains | |
350 | VALUE (a regexp), store the messages as specified by SPLIT. | |
351 | ||
352 | \(| SPLIT...): Process each SPLIT expression until one of them matches. | |
353 | A SPLIT expression is said to match if it will cause the mail | |
354 | message to be stored in one or more groups. | |
355 | ||
356 | \(& SPLIT...): Process each SPLIT expression. | |
357 | ||
358 | \(: FUNCTION optional args): Call FUNCTION with the optional args, in | |
359 | the buffer containing the message headers. The return value FUNCTION | |
360 | should be a split, which is then recursively processed. | |
361 | ||
362 | FIELD must match a complete field name. VALUE must match a complete | |
363 | word according to the `nnmail-split-fancy-syntax-table' syntax table. | |
364 | You can use \".*\" in the regexps to match partial field names or words. | |
365 | ||
366 | FIELD and VALUE can also be lisp symbols, in that case they are expanded | |
367 | as specified in `nnmail-split-abbrev-alist'. | |
