I had to set smime-CA-directory in my .gnus. I did this: (setq smime-CA-directory "/etc/ssl/certs/ca-bundle.crt") However, it seems to me that this is something that should probably be done by default by the Fedora packaging.
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.

I don't understand this report (which by the way was forwarded to http://debbugs.gnu.org/20960 ). On RHEL7 at least, /etc/ssl/certs/ca-bundle.crt is a (symlink to a) file, not a directory. So I can't see that the applied patch makes any sense. Maybe there was a typo in the original report? Perhaps "smime-CA-file" was intended?
My mistake... On Fedora, this should be (setq smime-CA-directory "/etc/ssl/certs/"). I'm not even sure why this was proposed to be "fixed" upstream, it looks like a downstream "configuration" to me. Thanks for pointing this out!
