Hi Alberto!
I will clarify my answer, sent to you by email.
My solution is not embeded into the text of RC. It consists of two plugins: one for message processing and another for certificates management.
However, I've added 3 new hooks, fixed one obvious mistake in the RC text and made one patch that requires discussion.
Without the participation of the team RC, these changes will not be made to the RC.
Therefore, at this stage is useless to publish my plugins. They simply can not be used.
Best regards, Vladimir Gorpenko
