SMTP Deux

SMTP Deux v1.1.0 is shipping

SMTP Deux is a 4th Dimension component which provides a complete implementation of the SMTP protocol. SMTP Deux works on top of the commercial TCP Deux 4D component, currently in beta from Deep Sky Technologies, Inc.

With the SMTP Deux component, a 4th Dimension developer has complete implementation of the SMTP protocol from within 4D. The protocol relies on the TCP Deux component for all TCP communication needs, thereby removing any reliance on current or future TCP plugins which are available for use in 4D. The implementation of SMTP within the SMTP Deux component also eliminates long bugs and anomalies that have existed in plugin implementations of the SMTP protocol.

The single greatest feature of SMTP Deux is that it does not use the SMTP layer within 4D Internet Commands. Over the years, many developers have encountered different bugs and anomalies within the SMTP implementation of 4D Internet Commands. SMTP Deux uses the routines within the TCP Deux component package for all TCP communications, which themselves only use the TCP layer within 4D Internet Commands when that plugin is in use. So, most if not all errors which 4D developers experience when sending email with 4D Internet Commands are removed when using SMTP Deux.

As well, SMTP Deux provides a full and complete implementation of the SMTP protocol. So, for those developers using either version of Internet ToolKit and experiencing difficulty setting up their own email sending routines, there is no longer any need to go through this hassle. SMTP Deux provides you with successive email sending routines so that you can choose the implementation that works best for your email sending needs.

SMTP Deux includes full compatibility with SMTP AUTH, authenticated login for SMTP servers. When enabled, SMTP Deux will choose the most secure means supported by the SMTP server to login. This includes CRAM-MD5, NTLM, Login, and Plain SMTP AUTH mechanisms. SMTP Deux is the only solution currently available for 4D developers that has full support for SMTP AUTH.

A full manual, explaining every call and feature available in SMTP Deux, is included with the component.

New Features in v1.1.0

Version 1.1.0 of the SMTP Deux component contains three important feature additions.

First, SMTP Deux now has full support for NTLM authentication with SMTP servers. NTLM is a common authentication scheme used by Microsoft products. This moves SMTP Deux further ahead again in offering features not available anywhere else in the 4D development environment.

Second, new utility routines for sending email have been included. These two new routines allow for single method access to send email with both text and HTML content. With a single call now, 4D programmers can send email in a standards complient format for both text email clients and HTML email clients.

Third, support for 4D v6.8.x is now available in SMTP Deux. New affix documents specifically for running under Carbon using 4D v6.8.x are available with this release of the component.

4D v6.8.x and MacOS X Compatibility

 SMTP Deux v1.1.0 - The latest release of this component is available for both 4D v6.7.x and 4D v6.8.x.

The SMTP Deux component has been fully carbonized. The current released version supports the carbonzied version of 4D, version 6.8.x. This provides seemless and transparent support for all of your 4th Dimension based applications on MacOS 8/9, MacOS X, and Windows 98/2000/XP/NT.

  • Single method access for sending HTML email;
  • Full support for one or more attachments;
  • Built in attachment encoding for error free operation;
  • Full support for SMTP AUTH;
  • Full support for NTLM, the proprietary SMTP AUTH scheme commonly commonly used by Microsoft products;
  • Full support for specifying content-type for attachments;
  • Full support for specifying content-type of email body (e.g. for HTML email);
  • Complete email header field control;
  • Utility routines for formatting and encoding attachments;
  • Utility routines for formatting recipients;
  • More than two dozen different email header lines supported;
  • Custom constants to speed the creation of complex emails;
  • Fully cross-platform and native implementation for SMTP protocol.
  • Support for 4D v6.8.x under Carbon, providing compatibility with MacOS 8/9, MacOS X, and Windows 98/2000/NT/XP.

The SMTP Deux component requires the TCP Deux component, version 1.0.1 or above, be installed to operate properly. TCP Deux is available from Deep Sky Technologies, Inc., and provides TCP communications functionality needed for the implementation of the SMTP protocol.

The SMTP Deux component also requires the BASh component, version 1.6.3 or above, be installed to operate properly. BASh is available from Deep Sky Technologies, Inc., for free and provides an extensive set of functionality to any 4D based project.

Pricing and Availability

The SMTP Deux component is available for free to all owners of TCP Deux. There are no licensing or deployment restrictions of any kind for the SMTP Deux component.

Download SMTP Deux Now

The licensing schema for SMTP Deux gives you direct access to both platforms for the component.

Both formats though include copies of the SMTP Deux component and the full manual documenting all of the routines and features available.

 SMTP Deux Demo v1.1.0 - This demo provides a very interface for sending email. It shows how simple it is to set up the interface and code for sending email from within 4D. Code within the database provides examples of using all of the different routines in the SMTP Deux component, including the Send Complex routines available in the component. The demo is provided in both interpretted and compiled mode for you to work with and study.

SMTP Deux Professional

So, you don't like the idea of not having access to the source code? Or, do you have a client that demands full source for all tools that you use in their 4th Dimension based product? Maybe you just like the feeling of extra protection in knowing that you have the full source for your 4D based applications.

SMTP Deux Professional is for you! SMTP Deux Pro is a full source code licensing option for the SMTP Deux component. Unlike the freely available SMTP Deux component, though, licensing for SMTP Deux Pro is subscription based. The pricing for SMTP Deux Pro is targetted particularly for the professional 4D developer or client that requires full source access within their 4th Dimension based systems.
