[kwlug-disc] msmtp email to gmail not landing - ideas?

[B. S.]

I believe this has now probably been solved.

gmail wants addresses in the body of the message, not just the headers.

So: echo Body | sendmail -s Subject recipient at example.com

is insufficient, even though all msg headers are proper.

Instead: echo -e "From: me at mine.com\nTo: the at other.guy\nSubject: 
Topic\nBody" | sendmail recipient at example.com
