The release engineers have asked me to put together a patch for RELENG_4 that captures the most important security checks added to 8.12.10. Given the closeness of the 4.9 release, there wouldn't be enough time to test a complete MFC of 8.12.10. If you have some time during the day Wednesday, please test the patch at: http://people.freebsd.org/~gshapiro/sendmail.diff Unfortunately, I won't be able to accommodate requests to add other changes that people want from 8.12.10. The full 8.12.10 MFC will happen after the RELENG_4 code freeze is lifted. If no problems are found, the patch will be committed Wednesday evening.
