David,
I did not look up all the links you sent, but I had visited at least
some of them. The messages with the links are here in my Mutt
directory. Thanks.
I understand your advice, and I am not going to reinstall Debian. I
have not been able to figure out how to get the Evolution system
running again. HostGator may have a web interface I can use
meanwhile.
I hesitate using Mutt to directly retrieve the messages from Hostgator.
My system uses getmail to fetch from the server at the ISP; and I am
reluctant to mess with a system which is working and on which I rely.
