Secure Messaging is a Web-based, alternative mail system for sending and receiving messages.

Use secure messaging to send and receive messages from a alternative web-based mail system. Using the secure messaging system no actual mail is transmitted through any 3rd party servers.

Only an optional message notice is sent to the recepient, the user needs to visit the site in order to read the message.

Normal SMTP mail can hit multiple servers and can possibly be read, stored, or changed anywhere within the process.

Setup secure messaging on an SSL enabled website to enhance the privacy even more.

SideSMS sends SMS trought Italian sites and if requests works as interface for smssend.

SideSMS use italian gateways for sending SMS. Its multiplatform. SideSMS has a lot of features for sending and managing sms and accounts.

SMS Framework is an Objective C framework for decoding SMS messages in PDU format to objects.
It is easily usable in Cocoa and GNUstep environments, and it reduces developer responsibility for decoding messages to extracting the raw messages from the phone.
The XCode project file contains three targets: one system wide framework, one framework to include in applications, and a small application for testing the framework.
Enhancements:
- Fixes two small bugs in decoding that seem to affect international users.
- The bugs became apparent after OS X 10.4.5 appeared.

Kannel WAP and SMS Gateway project is a WAP and SMS gateway.
SMS, short message services, are widely used all over the world in huge amounts. The main use for Kannel is to link HTTP based services to various SMS centers using obscure protocols.
WAP, short for Wireless Application Protocol, is a collection of languages and tools and an infrastructure for implementing services for mobile phones. Traditionally such services have worked via normal phone calls or short textual messages (e.g., SMS messages in GSM networks). Neither are very efficient to use, nor very user friendly. WAP makes it possible to implement services similar to the World Wide Web.
Unlike marketers claim, WAP does not bring the existing content of the Internet directly to the phone. There are too many technical and other problems for this to ever work properly. The main problem is that Internet content is mainly in the form of HTML pages, and they are written in such a way as to require fast connections, fast processors, large memories, big screens, audio output, and may require fairly efficient input mechanisms. Thats OK, since they hopefully work better for traditional computers and networks that way. However, portable phones have very slow processors, very little memory, abysmal and intermittent bandwidth, little screens and extremely awkward input mechanisms. Most existing HTML pages simply will not work on them.
WAP defines a completely new markup language, the Wireless Markup Language (WML), which is simpler and much more strictly defined than HTML. It also defines a scripting language, WMLScript, which all browsers are required to support. To make things even simpler for the phones, it even defines its own bitmap format (Wireless Bitmap, or WBMP).
HTTP is also too inefficient for wireless use. By using a semantically equivalent, but binary and compressed format it is possible to reduce the protocol overhead to a few bytes per request, instead of up to hundreds of bytes. Thus, WAP defines a new protocol stack to be used. However, to make things simpler also for the people actually implementing the services, WAP introduces a gateway between the phones and the servers providing content to the phones.
The WAP gateway talks to the phone using the WAP protocol stack, and translates the requests it receives to normal HTTP. Thus, the content providers can use any HTTP servers, and can utilize existing know-how about HTTP service implementation and administration.
In addition to protocol translations, the gateway also compresses the WML pages into a more compact form, to save bandwidth on the air and to further reduce the phones processing requirements. It also compiles WMLScript programs into a byte-code format.
Requierments:
- C compiler and development libraries and related tools.
- The gnome-xml (a.k.a. libxml) library, version 2.2.0 or newer. We recommend that you use libxml version 2.2.5. If you are installing it from your distributions packages, youll need libxml2-dev in addition to run-time libxml2 package libraries.
- Note: there is a bug in libxml version 2.2.3 and 2.2.4 that causes problems with character encoding in attributes. This problem is fixed in 2.2.5. See http://xmlsoft.org/xml.html.
- GNU Make.
- POSIX threads (pthread.h).
- GNU Bison 1.28 if you modify the WMLScript compiler.
- DocBook markup language tools (jade, jadetex, DocBook style-sheets, etc; see README.docbook), if you want to format the documentation (pre-formatted versions are available).
Enhancements:
- Various critical bugfixes since 1.4.0, including major SMSC protocols supported (SMPP, EMI/UCP, and GSM AT modem comands), HTTP layer fixes, and WAP WTP and WTP SAR layer fixes.
- The sendsms HTTP interface has been improved to obey the bearerbox message state for replies.

Clickatell SMS API provides a tool for sending SMS messages using the Clickatell gateway.
It provides support to authenticate to this service and query for the current account balance.
This class use the fopen or CURL module to communicate with the gateway via HTTP/S.
Enhancements:
- Fixed bug in function encode_message (tnx Neil)

o2-sms.pl is intended for customers of O2 Germany that have an account at www.o2online.de. o2-sms.pl can send SMS messages via the WWW gateway.
Use the -f option to send a flash SMS (it will pop up on the recipients display immediately).
The message text can have up to 780 characters. SMS to wired recipients are limited to 160 chars, as they are being sent as "text-to-speech".
Main features:
- sends SMS to ALL german cellphone networks and text-to-speech messages to wired recipients - now you can reach nearly everyone
- supports Flash SMS
- fakes user-agent by selecting one out of currently 10 "real" agents (IE, Mozilla, Opera et al.)
- very fast and reliable message delivery
- can be modified to use with other networks
- fully emulates a web user filling in the HTML form

SMS Server Tools package contains applications to send and receive short messages through GSM modems or mobile phones. The user can send short messages by simply storing text files into a special spool directory.
The program monitors this directory and sends new files automatically. It also stores received short messages into another directory as text files. The program can run other external programs or scripts after events like reception of a new message, successful sending, and when the program detects a problem. These programs can inspect the related text files and perform automatic actions.
Enhancements:
- Compared to version 2.x, this branch includes some enhancements for the UTF-8 character set and some experimental extras.
