examples/slimta-mail.py](examples/slimta-mail.py) provides a
fully functional mail server for inbound and outbound email. To avoid needing
to run as superuser, the example uses ports
It needs several things to run:
virtualenvas created above in Getting Started.
A TLS certificate and key file. The easiest way to generate one:
openssl req -x509 -nodes -subj '/CN=localhost' -newkey rsa:1024 -keyout cert.pem -out cert.pem
- A populated [
examples/site_data.py](examples/site_data.py) config file.
Check out the in-line documentation with
--help, and then run:
Manually or with a mail client, you should now be able to deliver messages. On
1025, messages will go to unique files in the current directory. On port
1587, messages will be delivered to others using MX records! To try out a TLS
$ openssl s_client -host localhost -port 1587 -starttls smtp
