+ * rmail-spam-filter.el: (vm-use-spam-filter)
+ (rsf-min-region-length-added-to-spam-list): New variables.
+ (rsf-bbdb-auto-delete-spam-bbdb-entries): Renamed from
+ rmail-bbdb-auto-delete-spam-entries. Added cc: to recipients for
+ spam testing. Don't delete spam message if automatic deletion
+ after output via variable rmail-delete-after-output is turned on.
+ (rsf-bbdb-dont-create-entries-for-deleted-messages): Renamed from
+ rsf-bbdb-dont-create-entries-for-spam.
+ (check-field): New function, extracted from code in
+ rmail-spam-filter to ease addition of header fields like
+ content-type.
+ (message-content-type): New variable to check the content-type:
+ field added, also in defcustom of rsf-definitions-alist.
+ (rmail-spam-filter): Replace repeated test code for header fields
+ by calls to check-field; change the call to
+ rmail-output-to-rmail-file such that rmail-current-message stays
+ the same to avoid wrong deletion of unseen
+ flags.
+ (rsf-add-contents-type): New function to convert old format
+ of rmail-spam-definitions-alist into new one.
+ Changed prefixes of all variables and functions from
+ rmail-spam-filter- or spam-filter- or rmail-spam- to rsf-.
