Can I send emails from my local smtp?

Question

Python

I have a local smtp server on aiosmtpd, how can I make it send emails to other servers like gmail? How can I do this and where to look, tell me the documentation.

import asyncio
import logging

from aiosmtpd.controller import Controller
from aiosmtpd.handlers import Sink
from smtplib import SMTP


async def amain(loop):
    cont = Controller(Sink(), hostname='127.0.0.1', port=8025)
    cont.start()


if __name__ == '__main__':
    logging.basicConfig(level=logging.DEBUG)
    loop = asyncio.get_event_loop()
    loop.create_task(amain(loop=loop))
    try:
        loop.run_forever()
    except KeyboardInterrupt:
        pass

client

import smtplib

s = smtplib.SMTP('127.0.0.1', 8025)
try:
    s.set_debuglevel(True)
    s.sendmail('[email protected]', ['[email protected]'], """\
    Date:17/05/2017,2:18
    From: [email protected]
    To: [email protected]
    Subject: A test
    testing
    """)
    s.quit()
except smtplib.SMTPException:
    print("Error: unable to send email")
    import traceback
    traceback.print_exc()
