[imp] Spam plug-in

[Matej Baćo]

I'm working on spam plug-in for IMP application. 

Plug-in needs to have 2 features: 
1. While the person is reading mail he can flag it as SPAM which will 
contact the remote service, register content of mail as SPAM and 
delete the message or put it in SPAM folder. 
2. When the person checks new mail, list should be check for SPAM by 
contacting remote service and deleting all SPAM mail or moving it to 
SPAM folder. 

Plug-in needs to be separated entity from IMP so it can be upgraded to 
newer versions etc. 

First I was thinking about using IMP hook as solution but realized the 
solution is not separated enough from IMP. Installation would require 
user to copy-paste php code. 

So now I'm researching solution as separated Horde application which 
will work inside IMP. Is this a good way and where to start? 

One important note. For bout features I need access mail message in 
raw format for example if it's an html mail I need all of his plain/ 
text parts (html and plain text). These parts are needed for remote 
SPAM service. 

Thank you for answers
