SMTP servers impletement base on Gevent

Install

pip install gsmtpd

Usage

Basically gsmtpd is ported from Python standard lib smtpd, you can it check from Doc_

however there is only one difference, you should add monkey patch of gevent

.. code-block:: python

from gevent import monkey
monkey.patch_all()

Example

.. code-block:: python

from gevent import monkey 
monkey.patch_all()
from gsmtpd.server import SMTPServer

class DebuggingServer(SMTPServer):
    # Do something with the gathered message
    def process_message(self, peer, mailfrom, rcpttos, data):
        inheaders = 1
        lines = data.split('\n')
        print '---------- MESSAGE FOLLOWS ----------'
        for line in lines:
            # headers first
            if inheaders and not line:
                print 'X-Peer:', peer[0]
                inheaders = 0
            print line
        print '------------ END MESSAGE ------------'

if __name__ == "__main__":
    
    server = DebuggingServer()
    server.serve_forever()
