please create a new file tracker-mbox.c

we will probably need tracker-mbox-evolution, tracker-mbox-thunderbird 
as well for their specifics

no it cant. Evolution, Thunderbird and KMail all store their mbox 
folders in certain locations and with certain names/extensions so its 
just a matter of watching those directories (recursively)

you will need functions for watching each type (WatchEvolution, 
WatchThinderbird etc)

mbox files can be dynamically added (eg in thunderbird or evo you can 
create new vfolders with their own mbox file) so the directory must be 
watched
