While it cannot guarantee a fix, Fortect is designed to repair and restore your system, ensuring that Windows and other programs run smoothly.

It can also automatically fix missing or corrupt DLL files, which could be contributing to the error. However, it is important to note that Fortect cannot fix hardware-related issues that may be causing the error.

python
import imaplib

def connect_to_imap_server(server, username, password):
try:
# Connect to IMAP server
imap_server = imaplib.IMAP4(server)

# Login with username and password
imap_server.login(username, password)

# Perform IMAP operations...
# ...

# Close the IMAP connection
imap_server.logout()

except imaplib.IMAP4.abort as e:
# Handle IMAP connection closure
print("IMAP connection closed:", str(e))

# Example usage
server = "imap.example.com"
username = "your_username"
password = "your_password"

connect_to_imap_server(server, username, password)

In the above code, a function `connect_to_imap_server` is defined to simulate connecting to an IMAP server using the provided server address, username, and password. It attempts to perform IMAP operations within a try-except block. If the connection is closed abruptly (`IMAP4.abort` exception), it catches the exception and prints a message indicating the IMAP connection closure.
