Workgroup email reply not working

[dt777]

Hello. I am helping a person set up workgroup messaging. I
have it working fine with Eudora 5.2.1. However, when the
person opens up the .mxm file with openmail and does a
reply, Eudora on that machine complains that it is not
being supplied with a To: address. Evidently MS Project is
not supplying a return email address in the file it sends
out. I have looked around MS Project and cannot find a
place to specify the email address of the current
registered user of project. Can anyone help? THNX
