Error: Could not convert socket to TLS

[Guest]

Last Friday, we changed TLS certs on mail server. Now scheduled mailings are not going out. I'm getting the following error in my mail.log file.

"Error","scheduler-0","06/03/13","14:24:56",,"javax.mail.MessagingException: Could not convert socket to TLS;   nested exception is:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"

Is Coldfusion caching the certs? How do get Coldfusion to recognize new cert?

I'm on CF10 and up-to-date on hotfixes.

Possibly relevant: someone else had an issue with a self-signed SSL certificate that they solved by importing the cert into the key store. http://forums.adobe.com/message/4246821
