On my machine that uses exim (used to send this mail), exim does not add a "Sender:" line. The exim4(8) man page says for the -f option: Processes running as root or the Exim user are always trusted. Other trusted users are defined by the trusted_users or trusted_groups options. In the absence of -f, or if the caller is not trusted, the sender of a local message is set to the caller's login name at the default qualify domain. But if you set use_envelope_from in Mutt, the -f option will be used (see OPTENVFROM in sendlib.c). -- 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)
