IMAP Debug - Yash-777/Java_Mail GitHub Wiki

From my point of view these are Some of the following scenarios where the server is not accessible:

  1. We need to check the CLIENT/USERS machines inbound and outbound ports and IP’s are enabled/added.
  2. Form Client Machine Use PortQuery to check IP with Port is accessible or not.
  3. Last Check We need to check the outside access is enabled or not from Mail Server Side.
