And ATS followed through with the following link: http://www.eudora.com/techsupport/kb/2323hq.html . However, a) I don't know how any ordinary person who stumbles upon this error would find their way to this link (or should I have just Googled it myself?), and b) the linked page addresses the error "SSL Negotiation Failed: Certificate Error. Cert Chain not trusted. Try adding this certificate to your certificate database for SSL to succeed Certificate Error," instead of the error that I got, which was, "Certificate bad: Destination host name does not match host name in certificate," so I do not know yet if those instructions actually help in this case. -- dkm David McFarlane wrote: >Of course, I did not get Gary's message until after I got this error >myself and called it into ATS Help.
