We prepered newsletter for one of the public person for his advertising campaing. The newsletter was sent by our newsletter system to several thousand people.

We've created mail server in JAVA which stores messages in chunks in order to provide better security and integrated it with existing webmail system written in JavaScript and PHP. The system uses multiple servers in order to increase fault tolerance but it stores messages encrypted and splitted in order to prevent data leak in case of break-in. Unencrypted messages are never stored on disk, they are decrypted and joined only before presenting them to user. Servers constantly monitor their status and in case of faults they automatically start sending chunks of messages to other servers so that in case of next server breakdown there is no data loss. Because it's hard to search inside encrypted and splitted messages we've integrated Apache Solr search server into webmail system. Messages are indexed during sending but it doesn't allow to retrieve literal message contents. We've also added payments system for sending messages and extending message storage time. Senders can also see if recipient read the message or deleted it. Messages are automatically deleted after seven days, so if it's something important, sender can try to resend the message. This system is integrated with existing webmail system and users don't need to register separately in this system. Their settings and address book are automatically moved, but messages are stored separately.

We've modified look of a web email system. New templates required modification of JavaScript code which creates user interface in order to add new effects.

We've created iPhone application which allows users to read messages from their webmail account. This application remembers users' login and password for faster access and provides Apple Push Notification to notify about new mail. Application required integrating with existing webmail system and mail server. This allows us to send notifications as soon as mail is received instead of polling for new messages. If app user is currently viewing messages list application refreshes it only when it receives notification about new message. This way we don't use too much of users' bandwidth. Users can also send new messages from their phone or register new account if they didn't yet.
