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+
Usage
- Create a config file (see below).
- 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>.
Configuration
An example config file for a mailproxy instance that accepts emails locally on port 25 for delivery via Gmail appears below:
[local]
host = 127.0.0.1
port = 25
[remote]
host = smtp.gmail.com
port = 465
use_ssl = yes
starttls = no
smtp_auth = yes
smtp_auth_user = USERNAME
