Notes about the JMS file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The JMS file type is primarily associated with 'SpamProx' by Dewqs' Tribes. File: FORBIDDEN.JMS. SpamProx is a mail proxy server. When the server sends an E-mail message, SpamProx analyzes it and tries to determine if it's spam.
