support proxy about aiosmtplib HOT 10 OPEN

To send via proxy you can use sock arg. For example:

from aiohttp_socks.proxy import create_proxy, ProxyType

proxy = create_proxy(
        host=proxy["hostname"], port=proxy["port"], proxy_type=ProxyType.SOCKS5)
await proxy.connect(host, port)

await send(
            message,
            hostname=None,
            port=None,
            validate_certs=False, # for validate server_hostname should be passed to starttls.
            username=source["username"],
            password=source["password"],
            start_tls=True,
            sock=proxy.socket
        )

Not currently, but I could have a look. What kind of proxy? SOCKS?

from aiosmtplib.

Http will be great, I'm using PySocks==1.6.7 to do the global http/socks proxy, but in production i just want to enable it for the email, I'll have a look at how to do the monkey patch correctly as well

from aiosmtplib.

Any changes?

aiohttp_socks looks deprecated it's proxy.socket functionality.
old version of aiohttp_socks does not allow to close socket

from aiosmtplib.

I was just going to add documentation for the sample above.

aiohttp_socks doesn't say deprecated in the repo, but it hasn't been updated in a while.

Oh yes I see.

Does aiosmtplib.send close connection ?
I see a lot of problems with duplicating FD's when I pass a sock I got from aiohttp_socks's open_connection -> writer -> .get_extra_info('socket'). It looks like lib closed the socket, but did not tell asyncio to delete the FD (writer.close()).

Socket I put as param to .send method has FD equal -1 after send operation.

Can you give example of usage aiosmtplib with socks, please?

from aiosmtplib.

@starfear the only example I have is the one above.

The send API opens and closes the connection to the server each time it's called. I'm not sure how we would close the writer if you're just passing the socket.

Using the SMTP client class directly (https://aiosmtplib.readthedocs.io/en/latest/client.html) should give you control over when the connection is opened/closed so you can sync it up with the proxy connect.

Will this feature be added soon? Are there any alternatives to the above example?

And can you provide some information for adding proxy support to the library yourself?

from aiosmtplib.

Probably not unless someone is interested in contributing it. I'd accept a PR for documentation of how it works.
