Deep Sky Technologies has released SMTP Deux 1.0.0 (yep, two zeros there) for Macintosh and Windows.

It's a 4th Dimension component that offers 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, according to MacTech magazine (

With the SMTP Deux component, a 4th Dimension developer has a complete implementation of the SMTP protocol from within 4D. The protocol relies on the TCP Deux component for all TCP communication needs, which gets rid of any reliance on current or future TCP plug-ins that are available for use in 4D. The implementation of SMTP within the SMTP Deux component also eliminates long-standing bugs and anomalies that have existed in plug-in implementations of the SMTP protocol, the Deep Sky gang said.

SMTP Deux doesn't use the SMTP layer within 4D Internet Commands, but instead 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 plug-in is in use. The result, according to Deep Sky: most, if not all errors that 4D developers experienced when sending email with 4D Internet Commands are removed when using SMTP Deux.

SMTP Deux also offers a complete implementation of the SMTP protocol. And it includes full compatibility with SMTP AUTH, authenticated login for SMTP servers. Finally, it provides a complete implementation of the SMTP protocol within 4D.

The SMTP Deux component is available for free to all beta testers and owners of TCP Deux. It can be downloaded by following the Downloads link on the Deep Sky Web site.
