Lotus Development Corp has announced Lotus Notes 3.1 for Sun Microsystems Inc’s Solaris 1.1 Unix – and Sun plans to bundle it with all servers shipped before June 30. The Cambridge, Massachusetts company also announced the Notes SMTP Simple Mail Transfer Protocol gateway, to provide seamless interoperability between Notes mail and Unix mail users. The gateway also will provide MIME Multipurpose Internet Mail Extension support for handling of file attachments between disparate electronic mail systems. The gateway will ship within 60 days. Sun’s free Notes deal consists of a coupon for Notes server software plus six Notes client licences, worth almost $3,000, to be bundled with all Sparcserver systems shipped in the US, the UK, Canada and Germany between March 9 and June 30. Customers will be able to redeem these coupons for Lotus Notes at no charge until December 31. Notes 3.1 under Solaris 1.1 operates as a native Unix application with full support for the Motif interface and TCP/IP network protocol and is designed to interoperate seamlessly with Notes 3 under all supported Notes environments, including Windows, OS/2 and Macintosh System. Notes for Solaris also will work seamlessly with a number of X terminals. Notes for Unix supports Lotus Link, Embed and Launch-to-Edit, developed with Sofware Pundits Inc, providing object linking and embedding capability claimed to be equivalent to and compatible with Object Linking & Embedding 1.0 in Microsoft Corp Windows 3.1.
