Error connecting IMAP server with python imaplib and mailcow

I just install a mailcow mail server on a ubuntu 22.04(fresh install) vps, i can connect well with my mail client (Evolution), but have issue when trying to connect from a python script using imaplib:

my client side is Ubuntu 22.10 Mate with Python 3.10

import imaplib 
imap = imaplib.IMAP4_SSL("mail.mysite.com", 143) 
imap.login('[email protected]','a_strong_password')

getting this error:

Traceback (most recent call last):   
File "/home/cc1/python/mail/imap_test.py", line 12, in <module>
     imap = imaplib.IMAP4_SSL("mail.mysite.com", 143)   
File "/usr/lib/python3.10/imaplib.py", line 1323, in __init__
     IMAP4.__init__(self, host, port, timeout)

     self.open(host, port, timeout)

     self.sock = self._create_socket(timeout)   
File "/usr/lib/python3.10/imaplib.py", line 1327, in _create_socket
     return self.ssl_context.wrap_socket(sock,   
File "/usr/lib/python3.10/ssl.py", line 513, in wrap_socket
     return self.sslsocket_class._create(

     self.do_handshake()

     self._sslobj.do_handshake()
 ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:997)

I already try using ssl context with both options:

# PROTOCOL_SSLv23
# PROTOCOL_TLS
# PROTOCOL_TLS_CLIENT
# PROTOCOL_TLSv1
# PROTOCOL_TLSv1_1
# PROTOCOL_TLSv1_2

here the config of my mail client working well: mail client

i guess its about some server side config, but i'm new to mailcow and dovecot

Just find out my problem:

replacing imap = imaplib.IMAP4_SSL("mail.mysite.com", 143) by imap = imaplib.IMAP4_SSL("mail.mysite.com")

and then it works well
