The supplied Sony Ericsson PC Suite enables
email to be synchronized with Microsoft
®
Outlook
®
and Lotus
®
Notes
®
. During synchronization, new
email from the PC is transferred in to the corre-
sponding 'synchronized email account' inbox on
P990i. Messages and replies written using this
account on P990i are transferred and sent via the
PC.
Web based email can, of course, be accessed
using the P990i browser.
Email folders
Messaging accounts have the following folders:
Inbox, Outbox, Draft and Sent. You can create
additional folders if you want, see Local folders
below.
Remote folders
IMAP4 accounts can subscribe to remote folders
that are located on the server. Select subscribe
from the folder menu.
Local folders
To improve the organization of your folders you can
create more folders locally on P990i. Local folders
are only visible in the Messages application. Local
folders cannot be created on the Memory Stick™.
Push email
Push email is a method of 'pushing' or forwarding
email to mobile devices as soon as a message
reaches the email server. These solutions may also
include calendar and contacts synchronization.
Push email solutions allow email messages to be
delivered in the background in the same way as
SMS or MMS.
P990i is prepared for these solutions and a rich set
of 3rd party applications are available from compa-
nies such as Extended Systems, Intellisync, JP
Mobile, Research In Motion (RIM)/Blackberry,
Active Sync, Seven, Smartner and Visto.
Push methods
The solutions use different methods to push the
messages, usually IP push, by listening to dedi-
cated ports when a session is active, this is similar
to instant messaging solutions. Some solutions
may also use SMS with triggers to the application
to start a sync/download, sometimes referred to as
pseudo-push.
Security
All solutions use end-to-end security using SSL,
3DES or AES encryption. Most solutions are based
on using a fixed password for push mail. Initially
key exchange is also done by using device param-
eters such as the IMEI number. A few solutions
combine push with one-time passwords that are
limited for a certain amount of time before being re-
entered. Many solutions have functionality for
enforcing screen passwords. There is also some-
times theft and loss protection through wipe-out
commands and lock-out.
