Description Helmut Jarausch 2022-03-17 10:22:20 UTC 
In my private fetchmail Python script, I use
ssl_context = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
ssl_context.set_ciphers('AES256-SHA')

server = IMAPClient(HOST, ssl_context=ssl_context, use_uid=True, ssl=ssl)

This works just fine with Python3.9 and below.

But with Python3.10 I get

Traceback (most recent call last):
  File "/home/jarausch/bin/fetchmail_Skynet", line 171, in <module>
    server = IMAPClient(HOST, ssl_context=ssl_context, use_uid=True, ssl=ssl)

    self._imap = self._create_IMAP4()

ssl.SSLError: Cannot create a client socket with a PROTOCOL_TLS_SERVER context (_ssl.c:805)


Many thanks for some hints on what has changed in Python3.10 here.
