pipe-mail

A command-line tool to send e-mails via SMTP from the standard input.

Prerequisites

Node.js 7 or above.

Installation

npm install -g pipe-mail

Examples

You can directly send an e-mail from the command line:

echo "Hello world!" | pipe-mail -s Subject -o smtp.fastmail.com -u myusername -p mypassword [email protected] [email protected]

If you don't want to specify the server options every time, you can set them as environment variables:

export PIPEMAIL_SMTP_HOST=smtp.fastmail.com
export PIPEMAIL_SMTP_USER=myusername
export PIPEMAIL_SMTP_PASSWORD=mypassword
echo "Hello world!" | pipe-mail [email protected] [email protected]

You can feed any file to it to send the content via e-mail:

echo "Hello world!" > email.txt
pipe-mail [email protected] [email protected] < email.txt
