I think I've found out. It could be an option in Eudora about 'socket layers' If it's configured as ' use if available', it sends a CAPA request to the server, and generates the -ERR The message says that IMS does not understand the command 'in this state' Is there another 'state' or config in which CAPA commands are understood ? This is a mystery to me. Anyway, if Eudora socket layers option is set as 'never', no -ERR.
