skprmail

This project is a drop-in replacement for Sendmail which sends email via Amazon SES.

It reads a raw SMTP message from stdin and forwards it unaltered.

Installation

Download the binary for the latest release and place it at $(which sendmail).

Credentials

skpr config

The app knows how skpr mounts configuration into the container (via the mount at /etc/skpr). It picks up credentials from the following keys:

• IAM Key ID smtp.username
• IAM Key Secret smtp.password
• AWS Region smtp.region
• From Address smtp.from.address

Environment variables

• IAM Key ID SKPRMAIL_AWS_ACCESS_KEY_ID
• IAM Key Secret SKPRMAIL_AWS_SECRET_ACCESS_KEY
• AWS Region SKPRMAIL_AWS_REGION
• From Address SKPRMAIL_FROM_ADDRESS

Testing Locally

Create a file /tmp/test-mail.txt with the following contents. Adjust from/to address to those which are verified in SES.

To: my@email.com
Subject: sendmail test two
From: me@myserver.com

And here goes the e-mail body, test test test..

export SKPRMAIL_AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
export SKPRMAIL_AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
export SKPRMAIL_AWS_REGION=us-east-1
export SKPRMAIL_FROM_ADDRESS=admin@previousnext.com.au
