Some Internet Service Providers (ISPs) require you to use a specific Computer Name to identify your Computer and validate your account. This Error may appear as follows:

  • Error 500 5.5.2 bad chars in command
  • Error 501 5.5.4 Invalid Address
  • 501 Syntax error parameters or arguments to HELO command

Please check that your Computer Name contains only English letters:

  1. Right-click on 'My Computer' and choose 'Properties'.
  2. Under the Computer Name tab, click 'Change'.
  3. Delete the old Computer Name, and enter a new one. The name cannot contain special characters, such as the following:

    à â ç î ï ô ù û ü ; : " * + = | ?,

  4. Click 'OK' to close each dialog. You may need to restart your computer to finalize these changes.
