What is a JMS file

JMS files mostly belong to 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.

How to open a JMS file

You need a suitable software like SpamProx to open a JMS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your JMS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a JMS file directly in the browser:. Just drag the file onto this browser window and drop it.

How to solve problems with JMS files
