GROUP: Mail will be stored in GROUP (a string).
\(FIELD VALUE SPLIT): If the message field FIELD (a regexp) contains
VALUE (a regexp), store the messages as specified by SPLIT.
\(| SPLIT...): Process each SPLIT expression until one of them matches.
A SPLIT expression is said to match if it will cause the mail
message to be stored in one or more groups.
\(& SPLIT...): Process each SPLIT expression.
\(: FUNCTION optional args): Call FUNCTION with the optional args, in
the buffer containing the message headers. The return value FUNCTION
should be a split, which is then recursively processed.
FIELD must match a complete field name. VALUE must match a complete
word according to the `nnmail-split-fancy-syntax-table' syntax table.
You can use \".*\" in the regexps to match partial field names or words.
FIELD and VALUE can also be lisp symbols, in that case they are expanded
as specified in `nnmail-split-abbrev-alist'.
GROUP can contain \\& and \\N which will substitute from matching
\\(\\) patterns in the previous VALUE.
Example:
\(setq nnmail-split-methods 'nnmail-split-fancy
