Documentation:
An alist for selecting preferred attribution based on mail headers.
Each element of this list has the following form:

(INFOKEY ((REGEXP . ATTRIBUTION)
(REGEXP . ATTRIBUTION)
(...)))

Where INFOKEY is a key for `sc-mail-field', REGEXP is a regular
expression to match against the INFOKEY's value. ATTRIBUTION can be a
string or a list. If it's a string, then it is the attribution that is
selected by `sc-select-attribution'. If it is a list, it is `eval'd
and the return value must be a string, which is used as the selected
attribution. Note that the variable `sc-preferred-attribution-list'
must contain an element of the string "sc-consult" for this variable
to be consulted during attribution selection.

You can customize this variable.
