Anyone interested in creating plug-ins for Eudora 3.x that provide encryption/remailer/etc support needs this information. dave ................................. cut here ................................. ABOUT THE API The EMS API is one of several complimentary facilities available for integrating 3rd party applications and services with Eudora email. "Plug-ins" interface with Eudora via the EMS API. For Windows the plug-ins are DLL's and on the Macintosh they are Components. Abstractly speaking, the EMS API is most suited for performing transformations, conversions and some other forms of processing on email messages as they are sent and received by Eudora. In practice it is very useful for encryption, digital signatures, and compression. These are all processes that involve encapsulating a message attachments and all. The EMS API is also very useful for text processing and conversions. These might include simple formatting and sorting utilities, or human language translation, and some forms of text-based encryption. EMS API plug-ins can be used to do data format conversions on things ranging from graphic images in attachments to international character sets. Another interesting category are plug-ins that process messages in some way, but don't necessarily change them. For example, a plug-in could be set up so that it scans certain messages for updates to a database like a catalog and automatically makes the change in the local database. Another could be used to scan incoming message attachments for viruses. In a sense, plug-ins can function as filters. DOCUMENTS AND SDK As of the end of July we have documentation and support available at <ftp://ftp.eudora.com/quest/emsapi> as follows: emsapi1.pdf - Adobe Acrobat document describing API version 1 (current on Mac) emsapi2.pdf - Acrobat document describing the API version 2 (current for Windows) chngs2.pdf - Acrobat document showing changes between version 1 & 2 EMS-API-SDK-1.0b3.hqx - Macintosh developer's kit ems1b2.zip - The Windows software developer's kit The developers kit includes a number of support utilities and source code for four sample plug-ins. CURRENT STATUS As of the end of August, Macintosh Eudora Pro 3.0 is shipping and supports the EMS API version 1. The current Macintosh Eudora Lite (the free version) does not support the EMS API, but it will and a beta version is expected in early September if not sooner. Version 1.0b3 of the SDK for the Macintosh is currently available from our FTP site. Windows Eudora 3.0 is in beta test right now and supports EMS API version 2. A copy can be obtained from our ftp site. Version 1.0b2 (a public beta release) of SDK for the API is also now available from our ftp site.
