Introduction

• Http//zandermail.sourceforge.net
• Email Agent, which makes possible to receive and
  send emails with any terminal equipment.
• Makes possible to receive and send emails from
  different mailboxes in the same GUI. Example You
  could read your schools INBOX,works INBOX and
  ISPs INBOX at the same time
• Very flexible and easy to change interface, so
  user can basicly determine what kind of user
  interface he/she wants...

Introduction (cont.)

• Open Source, so you can create own modules or
  examine the implementation.
• Is implemened with Object-Oriented paradigm,
  eventhough PHP is a scripting language
• ServerSide program, so you dont need to install
  any extra software on your terminal equipments.
• Requirements
• mySql - database
• Apache (or another) web server
• PHP 4.0.6 Module, or newer.
• Linux Send mail
• (will change so that is possible to run on top of
  Windows)

Introduction (cont)

• Zander Mail view of the one mailbox, with MSIE
  profile.
• Note that you can build your unique view for
  every browser.

Introduction (cont.)

• Here is the default profile view with wap7110.
  Note that 8ball.wbmp is an attachment, which you
  can view.

WAP Architecture (cont.)

• When wanted to use ZanderMail, you must call to
  the Dial-in server, your ISP or phone company has
  provided. That server then connects to the
  Gateway youve chosen (basically the IP of the
  gateway and the number of the dial-in server,
  comes with in the WAP-properties of your
  wap-phone). The gateway then connects to the
  server running zandermail with normal http
  request. The zandermail agent returns a http
  response to the gateway, which converts it to wsp
  (wireless session protocol ) response. The data
  itself is coded to binary strings either by the
  server or the gateway. The terminal equipment
  (TE) the interpretes the binaryXML (wml decks and
  cards) as implemented by the browser vendor.

Architechture

• User- and TE-identification are the basis of the
  ZanderMail Architechture, which allows the user
  to read/send emails with different Terminal
  equipments

Architechture (cont.)

• The login page is the entering point to the
  system. When user enters to the login page a
  temporary profile is created, from the xml formed
  default profiles(library.xml). The profileMapper
  assignes a certain profile to a certain user,
  based on the user-agent environment variable. If
  the user-agent string says nokia and a certain
  profiles mappedName attribute is nokia, this
  profile is assigned to the user.
• Profiles also determine what language is
  outputted, (output- attribute). In this case it
  would be WML. Profiles also include many other
  usefull attributes. When a profile is assigned by
  the system, it is saved to the user when logging
  in. The system produses a collection of different
  profiles to each user, whenever user enters to
  the system with different TE. User can also make
  its own profiles if suitable is not provided. The
  profile is used outputting trought out the
  session.

Architechture (cont)

• MailBox context is not a similar than usual
  mailbox. ZanderMailbox is global, so you can add
  any mailbox from any server to your mailPool,
  which contains all you mailboxes.

MAILPOOL
Page- Formatter uses Profile assigned
Commercial
ISP
TE
Work
School
Example -gtServer jasu.ath.cx userName
imap_testi passwd imap port 143
11
Architechture (cont)

• User can define number of mailboxes to use, These
  all are saved to the mailPool. ZanderMail uses
  IMAP protocol to access these boxes, which are
  physically located in different servers trough
  out the world (also local mailboxes can be added)
  
• Modifying the profiles user can define the view
  he/she wants. All boxes can be seen at the same
  time, or a generic menu is created if wanting to
  view boxes one at a time.
• Password of the remote boxes are encrypted to the
  database, so you are the only one who knows the
  key (your system password) needed to decrypt the
  passwords...

Security

• Security of the system
• As mentioned earlier the password of the remote
  boxes are encrypted to database.
• The data in session is saved to a table, so the
  default save.session handler have been replaced
  to quarantee to safeness of the session
  variables.
• IMAP over SSL is supported
