            Bug ID: 200903
           Summary: sendmail default configuration was broken by
                    FreeBSD-SA-15:10.openssl
           Product: Base System
           Version: 10.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: conf
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: vsasjason at gmail.com

I'm running default sendmail configuration just for forwarding mail for
logwatch. The /etc/mail/certs/ directory doesn't contains dh.param file, so
sendmail tries to use some internal default that is shorter than 768 bits, and
I'm getting the following errors:
