I would like to publish my custom SpamAssassin plugin under the MIT licence on GitHub but I am not sure if it is possible. SpamAssassin is licensed under the Apache Licence 2.0 and vast majority of other plugins I saw were also using the Apache 2.0 licence. I am not modifying any SpamAssassin files, so I do not need to create any NOTICE file (user would just add my files to the their SpamAssassin).
As of my reading and understanding of these lincences, it should be possible. I am not experienced in this issue so I just wanted to make sure not to make any licensing sin.
So the question is, is it possible to licence my plugin under MIT?
