Bug 56187

Version:            (using KDE Devel)
Installed from:    Compiled sources

Some filtering and profile functionality that is present in KMail (and more ;-) ) would also be nice to see in KNode.

This includes:

1. Setting up filters for incoming/outgoing articles: alter the list of displayed headers; add custom headers
   (not globally for every newsgroup as it is in present implementation) etc. Adding volatile header (e.g. that
   depend on article being replied to).

   Rationale: Fido groups (at least here) have X-Comment-To: headers that contain the name and mail address of
   the person who posted the article that one replies to. In a new article, this is set to 'X-Comment-To: All';
   otherwise to somewhat like 'X-Comment-To: Vasya Pupkin <vasya@pupkin.ru>'. Also, the gateway to those groups
   requires authentification through 'Keywords: ' header, e.g. 'Keywords: 1234567890' (with magic number that
   authenticates a user). While I'd like to add such header to the articles to fido7.* newsgroups (where the
   gateway cuts it out), I don't want to disclose my key in other groups.

2. Using different profiles for posting to different newsgroups.

3. Selecting the quoting format. It has become a de-facto standard in fido7.* to have initials of the original
   poster in quoting instead of just plain '>'; e.g.:

--------------------------
   Vasya Pupkin wrote:

   AS>> Foo bar baz?
   VP> Blah blah blah...
--------------------------

   Note that 'VP>' is used to quote the original post; while the lines that were already quoted have just one
   more '>' appended. It would be nice to have quoting format specified with regexps. The default quoting
   regexp would be 

   Matches [.*] quote as [> ]

   while those I described above would be

   Matches [^([A-Z]{0,2})> ?] quote as [\1>> ]
   Does not match [^([A-Z]{0,2})> ?] quote as [\i> ]

p.3 would also be nice to see in KMail itself ;)
