Managing massive amounts of emails can be easier as QmailAgent helps you 
centrally manage and switch between different email accounts. Besides composing, 
reading and organizing emails, you can even directly attach files from the 
TS-431X when composing emails. The QmailClient companion app for iOS® or 
Androidâ„¢ works alongside QmailAgent to provide convenient access to multiple 
email accounts from your mobile devices. You can use QmailAgent together with 
Qsirch, which supports searching through the .eml files stored on the TS-431X; 
or quickly send emails to people and groups by using the Qcontactz app.

Notes Station helps organize notes for your personal and working life. You 
can easily edit text, insert images/files from the NAS, fine-tune images with 
the image-editing tool, create sharing links to share notes, backup/restore your 
notes with snapshots, and ensure privacy with password protection and 
encryption. You can also invite people to collaborate on notes for greater 
teamwork! Notes Station provides a safe and convenient way of taking notes that 
are fully under your control on your TS-431X's private cloud. 
Use NAS to expand other NAS capacity with VJBOD 
 
Besides using physical storage expansion enclosures, there is an additional 
option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is 
network-based JBOD, allowing you to expand the storage of a QNAP NAS with 
multiple QNAP NAS units. The TS-431X supports VJBOD to economically expand the 
storage capacity of other QNAP NAS with its unused storage, and you can simply 
create virtual storage pools and volumes on the virtual disks for operating NAS 
services.
