85 | If you'd like, for instance, one mail group for mail from the | |

96 | does not have to be called anything beginning with \"mail\", | |
97 | \"yonka.zow\" is a fine, fine name), and the second is a regexp that | |
98 | nnmail will try to match on the header to find a fit. | |
99 | ||
100 | The second element can also be a function. In that case, it will be | |
101 | called narrowed to the headers with the first element of the rule as | |
102 | the argument. It should return a non-nil value if it thinks that the | |
103 | mail belongs in that group. | |

440 | ||
6748645f | 441 | The format of this variable is SPLIT, where SPLIT can be one of |
eec82323 LMI |
442 | the following: |
443 | ||
444 | GROUP: Mail will be stored in GROUP (a string). | |
445 | ||
16409b0b | 446 | \(FIELD VALUE [- RESTRICT [- RESTRICT [...]]] SPLIT): If the message |
a1506d29 | 447 | field FIELD (a regexp) contains VALUE (a regexp), store the messages |
16409b0b | 448 | as specified by SPLIT. If RESTRICT (a regexp) matches some string |
f0529b5b | 449 | after FIELD and before the end of the matched VALUE, return nil, |
16409b0b GM |
450 | otherwise process SPLIT. Multiple RESTRICTs add up, further |
451 | restricting the possibility of processing SPLIT. | |
eec82323 LMI |
452 | |
453 | \(| SPLIT...): Process each SPLIT expression until one of them matches. | |
454 | A SPLIT expression is said to match if it will cause the mail | |
455 | message to be stored in one or more groups. | |
456 | ||
457 | \(& SPLIT...): Process each SPLIT expression. | |
458 | ||
459 | \(: FUNCTION optional args): Call FUNCTION with the optional args, in | |
460 | the buffer containing the message headers. The return value FUNCTION | |
461 | should be a split, which is then recursively processed. | |
462 | ||
16409b0b GM |
463 | \(! FUNCTION SPLIT): Call FUNCTION with the result of SPLIT. The |
464 | return value FUNCTION should be a split, which is then recursively | |
465 | processed. | |
466 | ||
23f87bed MB |
467 | junk: Mail will be deleted. Use with care! Do not submerge in water! |
468 | Example: | |
469 | (setq nnmail-split-fancy | |
470 | '(| (\"Subject\" \"MAKE MONEY FAST\" junk) | |
471 | ...other.rules.omitted...)) | |
472 | ||
eec82323 LMI |
473 | FIELD must match a complete field name. VALUE must match a complete |
474 | word according to the `nnmail-split-fancy-syntax-table' syntax table. | |
475 | You can use \".*\" in the regexps to match partial field names or words. | |
476 | ||
01c52d31 | 477 | FIELD and VALUE can also be Lisp symbols, in that case they are expanded |
eec82323 LMI |
478 | as specified in `nnmail-split-abbrev-alist'. |
479 | ||
480 | GROUP can contain \\& and \\N which will substitute from matching | |
481 | \\(\\) patterns in the previous VALUE. | |

484 | ||
