Kent Clarstroem and James Hsieh summed it up quite nicely.

A fully patched Sun sendmail should I think be about the same as 8.7.6
from
a security standpoint. Hopefully, you are fully patched (if you're not,
you should).
SMI-8.6 is based on the Berkeley sendmail 8.6, but has been retrofitted
with
a lot of 8.7's features and security updates and also has some
additional
capabilities to integrate with NIS, I believe.
I chose to upgrade to 8.7.6 because experience has shown that if a
security
problem with sendmail is discovered, Eric Allman (the keeper of
sendmail) is
generally faster at responding with a patch than Sun is. Also, this
allows
just about completely identical sendmail.cf files across mixed SunOS
5.x,
SunOS 4.1.x, and other systems. If you have SunOS 4.1.x systems laying
around, sendmail-8.7.6 is the only way to go in my book.
If you choose to move to 8.7.6, you can pretty much continue to use your
exisiting Sun supplied sendmail.cf file (provided it's the one that came
with the "SMI-8.6" sendmail and not the older V5-based Sun sendmail).
There
are a couple of lines you need to remove which make NIS references that
sendmail 8.7.6 doesn't understand. If you can afford a little
experimentation
time, you might want to try your hand at generating a newer sendmail.cf
file
using the utilities provided with the sendmail source.
> 2. I have Sendmail-8.8.2. Are there any problems with useing this ?
No, and there are a number of new features I'd like to try to use.
However,
I'm waiting for people to flush out 8.8.2 a little more before I move to
it.
Thanks also to:

and anyone I missed.

I've installed 8.8.2 and it's been running fine for over a week. There
was quite a bit of documentation/README's before I found the
nitty-gritty.
There's an op.ps in the doc/op directory, but it doesn't give the full
instructions to create the cf file.
There should be a brief set of instructions just to get it going. Here's
my quick & dirty version, but DO read the op.ps and the README in the cf
directory.
Go to the sendmail-8.8.2/cf/cf directory
m4 ../m4/cf.m4 generic-solaris2.mc > sendmail.cf
in the sendmail-8.8.2/src directory,
sh makesendmail
sh make sendmail install
make sure the sendmail.cf file created above is in /etc/mail
Again read op.ps
Hope this helps.
Good Luck :)
