Would you be so kind to tell where exactly to add one more parameter to make it working as stated in this stackoverflow?

Hey @ramazk I have seen that most complaints are about timeout parameter. I have tried to fix the script, without testing, and added timeout to the open() method. Would you mind checking if the error is still the same?

Hi @sstevan, I have tried version of the script above. It has SyntaxError on line 64, so I have changed ...,timeout) to ...,timeout=None). And received this error:
File "/Users/ramazk/Python/test-email2.py", line 75, in open SocksIMAP4.open(self, host, port, timeout) File "/opt/homebrew/Cellar/[email protected]/3.10.8/Frameworks/Python.framework/Versions/3.10/lib/python3.10/imaplib.py", line 312, in open self.sock = self._create_socket(timeout) TypeError: SocksIMAP4SSL._create_socket() takes 1 positional argument but 2 were given
May be you have ideas how to make it working? Thanks in advance.

same error
