Push Email - Sony Ericsson W950 White Paper

Preliminary version - PA4
If IMAP4 is used you can enable the IDLE com-
mand to keep connected to the email server. This
allows the server to push new messages directly to
the W950 as they arrive.
Email transmission is performed in the background,
making it possible to perform other messaging
functions during transmission.
A list of recently used addresses are available when
creating a message. W950 allows distribution lists
to be created and sender ID information is sent
with message alerts.
W950 can send any type of attachment, including
the following:
• Pictures.
• Video clips.
• Audio files.
• SIS files.
• JAR/JAD files.
• Themes.
• vObjects (vCalendar, vCard, vNote, vBook-
mark).

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.
W950 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 (Blackberry), Micro-
soft™ (Exchange ActiveSync), 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
A signature may be set up so that essential details
are automatically copied to the end of each outgo-
ing email.
The supplied Sony Ericsson PC Suite enables
email to be synchronized with Microsoft™ Out-
®
look™ and Lotus Notes
new email from the PC is transferred in to the cor-
responding 'synchronized email account' Inbox on
W950. Messages and replies written using this
account on W950 are transferred and sent via the
PC.
Web based email can, of course, be accessed
using the W950 browser.
Email folders
Messaging accounts have the following folders:
Inbox, Outbox, SIM, Draft and Sent. You can create
additional folders if you want, see Local folders
below.
Local folders
To improve the organization of your folders you can
create more folders locally on W950. Local folders
are only visible in the Messaging application.
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.
