        ** See #59885.

        ** Moved all of the mail specific filtering stuff from filter/* to
        here.  Renamed appropriately into em* space, etc.

        * em-filter-folder-element.c (emff_copy_value): implement for folders.

        * em-vfolder-rule.c (get_widget): read the vfolder glade from
        mail-config.glade.

        * mail-config.glade: moved the vfolder source selector here.

        * em-search-context.c: new mail search specific rule context.

        * mail-component.c (setup_search_context): use the new
        em_search_context.

        * vfolder-rule.c (validate): change error to mail context.

        * filter-folder.c (validate): change error to mail context.

        * Makefile.am (em-filter-i18n.h): added rule for i18n of mail
        filter type stuff.
        (libevolution_mail_la_SOURCES): added in the filter and vfolder
        rule stuff specific to mail.

        ** See #59885.

        * em-format-html-quote.[ch]: remove and remove from build, not
        used.

        * Makefile.am (libevolution_mail_la_LIBADD): add libeabutil and
        evolutionsmime.

        * mail-component-factory.c (factory): there is no mail_config
        anymore.
