Feed Reader , Multiple Mail-box Manager and A Book-mark manager .. All-In-One

Question

I'm looking for a software that runs under Linux which supports Feed Reading , multiple mail-box management and bookmark management all integrated in one Software ..

I don't know how the integration should look like or what features are there .. All i care about is a single software that allows me to Read My feeds ( Like i already do with Akregator ) , manage my mailbox accounts ( Like i already do with Kmail ) and of course do bookmark management ( in a smart and neat way )

Is there such a software out there ?

Thanks in-advance
