Thanks for the tip! I needed to add in that "auth creds" bit. I guess I thought I read that opensmtpd would use my user passwords by default.
Thanks, Joshua P.S. I also made a goof in my .msmtprc config file. I did a user jos...@gnucode.me, when I should have specified "user joshua". Now, I'm off to set up DKIM! -- Joshua Branson Sent from Emacs and Gnus https://gnucode.me https://video.hardlimit.com/accounts/joshua_branson/video-channels "You can have whatever you want, as long as you help enough other people get what they want." - Zig Ziglar
