from gevent import monkey
monkey.patch_all()Example
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()Performance
