After doing some research on sieve support with dovecot, I decided to implement it on a virtual machine for testing. I have everything working as expected, i.e. a script is uploaded onto the server, and the interpreter works correctly.
However, I'm having trouble understanding how I could disable an action, rather than an entire extension. For example, I need to disable the redirect action to prevent anyone creating a forward. This action so happens to be a part of the fileinto extension, which contains other actions that I would like to keep enabled. (Such as keep, and discard). After reading the RFC standards, I don't think this would be possible.
Out of curiosity, I've tried including the following line to see if I could disable it:
sieve_extensions = -redirect
However, as expected:
managesieve: Warning: sieve: ignored unknown extension 'redirect' while configuring available extensions
Because this is an action, not an extension.
Has anyone else run into this situation?
What are some approaches to solve this problem?
