Hello, I'm trying to use git send-email with msmtp, and I have added the following to my .gitconfig: [sendemail] smtpserver = "/usr/local/bin/msmtp" This seems to work fine, except that sometimes git dies unexpectedly after queuing a patch to msmtp: Died at /usr/local/Cellar/git/2.12.0/libexec/git-core/git-send-email line 1350, <FIN> line 3. I'm guessing there's some kind of race, because this is not 100% reproducible, sometimes succeeds while others simply dies with the above message. As you can imagine, this is specially annoying when sending patch series. Has someone seen similar issues when using send-email and msmtp? Am I missing something in my .gitconfig? Thanks, Roger.
