10.1-RELEASE-p12 broke sendmail. 10.1-RELEASE-p13 didn't fix sendmail.

You are correct -- the OS update didn't fix the problem. FreeBSD
Security Advisories and Errata Notices are usually very reliable in
terms of accurately describing how to solve the problems they address,
but they aren't infallible. This was a rare case where things went
However, the work-around given in the errata notice was in fact the
missing piece that did solve the problem. Or at least, the core of the
given instructions was.
Now, the EN was written by Greg Shapiro, who is the maintainer for
sendmail in the FreeBSD base system. He explains here how things went
but essentially he was confused by an update to the sendmail standard
config and startup scripts that had added autogeneration of TLS
certificates but not all the other parameters that could be used with
TLS. I think this led to the work-around instructions being overly
complicated. As you saw, it could be condensed down to:
openssl dhparam -out /etc/mail/certs/dh.param 2048
service sendmail restart
I could work that out for myself from what was written in the errata
notice, but that's because I've been dealing with sendmail config in
FreeBSD for years. I think that summary, or commands pretty much like
them, got posted to various mailing lists fairly soon after the EN came out.
There will probably be a revision to the EN fairly soon. It will likely
be released as a bundle with other SA's or EN's when those are ready to
go, to prevent excessive churn for people tracking release branches.
