Thanks for all your replies.

I do not normally use Eudora to send e-mails.
Cox is my usual email provider. I just happened to try
sending from Eudora, and thought something must be wrong
if one works while the other don’t on the same computer.

Which is a CQ2010 made by Compaq. Somehow HP is involved.
Windows 7 home Premium edition.
Both versions of Eudora are 7.1.0.9
I don’t know how to tell the version of advast.
It is Avast! Free AntiVirus 2015
I have been using it a long time. It says I have
2099 points whatever they are.
Somehow a truncated verson of McAfee installed itself. I plan to uninstall it

If I say “Yes” to the message asking if I want to
Trust the Server’s SSL certificate, I get : “Eudora has stopped working”
I am unsure what certificate it is talking about? The email provider
or the Eudora program.

I am beginning to suspect that I was supposed to do some kind of install
for my wife’s login. I never suspected it was ignoring anything,
because I could see when it scanned, all her emails were included.
I also suspect if I were to do this “install”, her Eudora would stop
working. I doubt she would appreciate that.
