Requires 1.1Mb of free RAM, and a minimum of System 7.1. Also, if you have changed your background color and Eudora has thus changed the line color automatically, there is a script to change it back. You can use this if you want to have a New Mail sound OR a Getting Attention sound but not both. Just set the one you don't want a sound for to play Sound of Silence. To install, just drag the sound over your system folder.
New messages sounds .
This Eudora plugin has 7 sounds to indicate new mail has arrived. 3 are voices. The eMailman character is a service mark of Andrew Starr. Other marks belong to their respective owners, either Andrew Starr, or others.
