Restmail – sendmail-compatible CLI for Gmail and outlook

4 months ago 3

restmail is a sendmail-compatible CLI using gmail & outlook rest APIs. It can be used for email automation, notifications and with git send-mail for sharing patches.

restmail requires only minimal authorization scope to send mail. No access to reading or deleting mail is needed.

# install to ~/go/bin ($GOPATH) go install github.com/tonymet/restmail@latest

Initial Provider Setup (gmail or outlook)

Initial setup is done once / provider. This configures oauth2 clientID & Secret

[email protected] CLIENT_ID=xxxxxx CLIENT_SECRET=yyyy restmail -configClient -provider gmail -clientId "${CLIENT_ID}" \ -clientSecret "${CLIENT_SECRET}" -f "${FROM}"

Once provider config is set up above, you need to do the oauth flow through a web browser. Setup is only done once or if the tokens are invalidated.

[email protected] restmail -setup -provider gmail -sender "${FROM}"

When this is complete, your auth-token & refresh-token are saved and refreshed automatically.

[email protected] [email protected] [email protected] echo "subject: test subject\n\ntest messagee" | go run . -f "${FROM} -provider gmail "${TO}" cc:"${CC}"

Git send-mail configuration

[sendemail] smtpServer = /home/USERNAME/go/bin/restmail smtpServerOption = [email protected] smtpServerOption = -provider smtpServerOption = gmail
