One of the gotchas with Riseup.net’s crabgrass install is that it is very much a pull technology. You have to remember to check your Crabgrass. I am forgetful sometimes. So I made a script called crab2mail to pull your crabgrass inbox into your email Inbox. This is a first release, hosted over on my gitorious. Do let me know if you find it useful or you'd like changes. I’ve at least one improvement in mind already.
