Also, I would like to hear more about : Boilerplate stripper AND Better content-filtering / handling error messages. Boilerplate stripping is trivial to understand. But, can anyone elaborate on Better content-filtering / handling error messages?
But boilerplate stripping is not necessarily trivial to implement, because it's not always clear what boilerplate is. I think it might be a good idea to save it off and provide a link rather than discard it, which leads to interesting questions of storage, shared links for true boilerplate (storage compression of repeatedly encountered text, yes, but more important the link will turn purple so you don't need to click on it in the next message from that user!), and user interface in general.
Content filtering is mostly going to be about MIME handling: choice of the appropriate text/* part and things like that, removing images/video/etc where the list prohibits them, converting HTML/ wordprocessor attachments to plain text, removing MIME parts whose Content-Type doesn't match filename or perhaps file(1) magic in the content, etc.
Just to mention it: IF we are going to add MILTER functionality, a MILTER would be perfect to do MIME handling.
If we are going to add a MILTER functionality, even anti-spam filters can be at the least implemented. Isn't it? Some days ago, we were discussing about MILTERs in anti-spam context right. Now, a piece of anti-spam AND anti-abuse can be implemented at this level! I have implemented a binary Bayesian classifier which classifies an email either spam or not spam. Using it, making use of the main keywords in the email as vectors and learning from the reportedly-spam emails from the logs, we can implement this. After classifying an email as spam, we can display a line, may be, as "This may be spam. Please be careful while clicking on links or replying to this email with sensitive information!". So, using this we can enhance the usage of MILTER at the same time doing the MIME handling. Correct me if I am wrong. :)
