Deep Sky Technologies, Inc., Announces Release of SMTP Deux v1.0.0

First Full Release of New 4th Dimension Component

Vero Beach, FL - Thursday, September 6th, 2001: Deep Sky Technologies, Inc., today announced the full release of SMTP Deux v1.0.0 for Macintosh and Windows. 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, 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.
