Sendmail patch; brings up a questions about buildworld

[Jonathan Horne]

with the sendmail patch that came out today, i ask this:

when in installed this machine as 6.1-RELEASE, i did a buildworld and 
buildkernel and updated to 6.1-STABLE.

question: if i choose Patch Solution 1 from 
http://security.freebsd.org/advisories/FreeBSD-SA-06:17.sendmail.asc, do i 
need to build a new kernel to go with this, or can i just build the world and 
be done with it?

thanhs,
jonathan
