I am writing some code that uses poplib and imaplib to collect emails through a proxy server.
I use the following to set up a proxy connection:-
import socks
import socket
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS4,proxy_ip,port,True)
socket.socket = socks.socksocket
Which I got from the stackoverflow post:-
http://stackoverflow.com/questions/3386724/python-how-can-i-fetch-emails-via-pop-or-imap-through-a-proxy
Then I make my connection with the email server:-
server = poplib.POP3(self.host, self.port)
server.user(self.username)
server.pass_(self.password)
I am testing my code in a unittest and have encountered a problem that I believe relates to my connection with the proxy not closing down properly.
An example is:-
I have set up the proxy connection and am trying to establish a connection with the email server. As part of the unittest I intentionally use an incorrect email server password. The poplib library throws an exception that it can't connect. I catch the exception in the unittest, then move on to the next unittest, trusting the poplib library would properly close my previous connection.
My understanding is that this is not a good thing and that I should be ensuring the email and proxy server connections are properly closed.
I know how to close the pop3 connection:-
server.quit()
But do not know how to close the connection with the proxy server or if I have to do so.
Could someone please help me with this question or with my understanding if that's where the problem lies :)
