It did have periodic patches as needed.

Call it what you will. I suspect that it has slipped by others.

You may want to mention this in the advisory.

Nope. The revised advisory published to -announce provided only one patch, at

ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-03:04/sendmail.patch

and it failed to apply completely. No other patch was offered. There
were replacement binaries for 5.0, 4.7, and 4.6, which does not go back
a full year.

There really should be support for each release for a year.
