96 | nnmail will try to match on the header to find a fit. | |
97 | ||

99 | called narrowed to the headers with the first element of the rule as | |

316 | GROUP: Mail will be stored in GROUP (a string). | |

a1506d29 | 319 | field FIELD (a regexp) contains VALUE (a regexp), store the messages |
16409b0b | 320 | as specified by SPLIT. If RESTRICT (a regexp) matches some string |
f0529b5b | 321 | after FIELD and before the end of the matched VALUE, return nil, |
16409b0b GM |
322 | otherwise process SPLIT. Multiple RESTRICTs add up, further |
323 | restricting the possibility of processing SPLIT. | |
eec82323 LMI |
324 | |
325 | \(| SPLIT...): Process each SPLIT expression until one of them matches. | |
326 | A SPLIT expression is said to match if it will cause the mail | |
327 | message to be stored in one or more groups. | |
328 | ||
329 | \(& SPLIT...): Process each SPLIT expression. | |
330 | ||
331 | \(: FUNCTION optional args): Call FUNCTION with the optional args, in | |
332 | the buffer containing the message headers. The return value FUNCTION | |
333 | should be a split, which is then recursively processed. | |
334 | ||
16409b0b GM |
335 | \(! FUNCTION SPLIT): Call FUNCTION with the result of SPLIT. The |
336 | return value FUNCTION should be a split, which is then recursively | |
337 | processed. | |
338 | ||
eec82323 LMI |
339 | FIELD must match a complete field name. VALUE must match a complete |
340 | word according to the `nnmail-split-fancy-syntax-table' syntax table. | |
341 | You can use \".*\" in the regexps to match partial field names or words. | |
342 | ||
343 | FIELD and VALUE can also be lisp symbols, in that case they are expanded | |
344 | as specified in `nnmail-split-abbrev-alist'. | |
345 | ||
346 | GROUP can contain \\& and \\N which will substitute from matching | |
347 | \\(\\) patterns in the previous VALUE. | |
