mailproxy

mailproxy is a simple SMTP proxy. It receives emails through an unencrypted, unauthenticated SMTP interface and retransmits them through a remote SMTP server that requires modern features such as encryption (SSL, STARTTLS) and/or authentication (SMTP AUTH). mailproxy is primarily useful for enabling email functionality in legacy software that only supports plain SMTP.

Requirements

• Python 3.5+
• aiosmtpd 1.1+

1. Create a virtualenv on python3.5 and switch to it.

   mkvirtualenv -p $(which python3.5) mailproxy

   workon mailproxy

2. Install requirements: pip install -r requirements.txt
3. Create a config file from config.ini.sample as config.ini
4. Run mailproxy from the command line, e.g. python mailproxy.py.

By default, mailproxy looks for a config.ini in its own directory. If you have placed your config file elsewhere, you can run mailproxy using python mailproxy.py <config_file_path>.
