"*Where the mail backends will look for incoming mail.

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.
+\(FIELD VALUE [- RESTRICT [- RESTRICT [...]]] SPLIT): If the message
+ field FIELD (a regexp) contains VALUE (a regexp), store the messages
+ as specified by SPLIT. If RESTRICT (a regexp) matches some string
+ after FIELD and before the end of the matched VALUE, return NIL,
+ otherwise process SPLIT. Multiple RESTRICTs add up, further
+ restricting the possibility of processing SPLIT.
\(| SPLIT...): Process each SPLIT expression until one of them matches.
A SPLIT expression is said to match if it will cause the mail
the buffer containing the message headers. The return value FUNCTION
should be a split, which is then recursively processed.
+\(! FUNCTION SPLIT): Call FUNCTION with the result of SPLIT. 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.
