So you will need to upgrade to 2.6 first if you want to use Sun's
Solaris Upgrade procedure.

The cleanest, most secure option would be to perform backups, esp.
of the passwd/group/shadow/hosts information, wipe the machine clean,
perform a *minimal* installation of Solaris 8 *without* sendmail.

Then install postfix (or qmail depending on your preference).
postfix has the benefit of being a bit more sendmail-compatible
and easier-to-understand.  qmail is possibly more scalable if
you move hundreds of thousands of mail messages per day.

http://www.qmail.org/

Both postfix and qmail have been engineered from-the-ground-up
to be secure.  The same cannot necessarily be said of sendmail.

If you want to go through with upgrading to Solaris 8, you may want
to just get another disk and do a new install of Solaris 8 on the
new disk (it helps if you have another otherwise identical computer
to do the install on).  Then you'll have a bigger disk, be able to
repartition if needed, and will still have the old disk with Solaris
2.5.1 to use (to continue service and as a reference of configuration)
while you are configuring the new disk with Solaris 8.

The word of the day is mispergitude

The GNU libc would have the headers and libraries, but again it is
safer and easier to use the Solaris headers and libraries on Solaris.

All of these (the Solaris /usr/ccs/bin tools, headers, and libraries)
should be on the Solaris CD to be pkgadd-ed.  However, the hard part
may be finding which of the packages include all of these things, and
possibly finding disk space for it all.  If that is too much of a problem,
get a new hard drive and install Solaris 8 on it (with SUNWCall cluster
to avoid this type of problem in the future).
