+Enter the app password
+
+How to store password to not require password entry every time email is sent?
+(At first tried adding libsecret, but that seems to require gnome-keyring. I added that and a bunch of dependent packages were also added. The keychain seems to be active but msmtp was still prompting for password. Then I learned the password could be added to the config file which is much simpler. Removing gnome-keychain for now since it adds a lot of unnecessary things.)
+
+Password can be added to config file such as:
+
+{{{
+nano ~/.msmtprc
+
+defaults
+tls on
+
+account gmail
+auth on
+host smtp.gmail.com
+port 587
+user wilsonwareapps@gmail.com
+from wilsonwareapps@gmail.com
+password ueut eapo jrqv eaid
+
+account default : gmail
+
+
+
+root@imx8mq-var-dart:~# msmtp -t < message.txt
+}}}
+
+E-mail sent successfully with no prompt for password
+
+This could be done from app code using a system call.
+
+
+How to send file attachments?
+
+msmtp does not have support for file attachments directly. The message must be encoded in mime format.
+
+Update message.txt to add MIME encoding
+
+{{{
+nano message.txt
+
+From: wilsonwareapps@gmail.com
+To: dwilson@cardet.com
+Subject: Test email from 825
+MIME-Version: 1.0
+Content-Type: multipart/mixed; boundary="MyBoundaryString"
+
+
+--MyBoundaryString
+Content-Type: text/plain
+Content-Transfer-Encoding: 7bit
+
+This is a message.
+
+--MyBoundaryString
+Content-Type: text/plain; file="file123.txt"
+Content-Disposition: attachment; filename="file123.txt"
+Content-Transfer-Encoding: base64
+
+}}}
+
+
+Create attachment file
+
+{{{
+nano attachment.txt
+
+This is an attachment
+123456
+abcdefg
+}}}
+
+Use base64 to convert the attachment to base64 encoding:
+
+{{{
+base64 attachment.txt > /tmp/attachment
+}}}
+
+Now pipe both files to the msmtp command
+
+{{{
+cat message.txt /tmp/attachment | msmtp -t
+}}}
+
+This successfully sends email with attachment
