Not as far as I know. I don't know much about Eudora. One way to encourage support for open source projects is to find the bug page / feature requests page and ask for the feature. While eudora is not open source they do have a feature request page: http://www.eudora.com/developers/feedback/ Also there is a plugin framework: http://www.eudora.com/cgi-bin/emsapi_download.cgi which says: | In practice it is very useful for digital signatures, | compression.and other things that involve encapsulating a message | attachments and all. The EMS API is also very useful for text | processing and conversions such as simple formatting and sorting | utilities, or human language translation, and some forms of | text-based digital signing. EMS API plug-ins can be used to do data | format conversions on things ranging from graphic images in | attachments to international character sets. which sounds quite full-featured so perhaps one could write a plugin using this API?
