Hi Trent, The latest git version of msmtp adds a 'buffer_mail' command and '--buffer-mail' option which tells msmtp to first buffer the complete mail in a temporary file before sending it.
Can you test if this works for you? Best regards, Martin -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
