Note that I replaced "does not work" by "may not work", because for maildir, mh (and IMAP), if there is a "Lines:" header, it will be used. The "Lines:" header can be generated with a procmail rule for instance, such as :0 Bfh * H ?? !^Lines: * -1^0 * 1^1 ^.*$ | formail -A "Lines: $=" But perhaps it should be :0 Bfh * -1^0 * 1^1 ^.*$ | formail -I "Lines: $=" (forcing a regeneration), because the provided "Lines:" header is not necessarily reliable. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
