Code:
df -k

Look for a filesystem at 100%.
It looks like may be /var full on you. Clean up time.

here is what if got after "df -k"

What should be my next step? Which one of the FSs should I clean up?

Code:
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0d0s0      4205630 4146189   17385   100%    /
/dev/dsk/c0d0p0:boot   11984    1593   10391    14%    /boot
/proc                      0       0       0     0%    /proc
mnttab                     0       0       0     0%    /etc/mnttab
fd                         0       0       0     0%    /dev/fd
swap                 2947316      24 2947292     1%    /var/run
swap                 2947292       0 2947292     0%    /tmp
/dev/dsk/c0d0s7      111909478 91741067 19049317    83%    /export/home

Well, your / directory is at 100%, and that's not very good.
/dev/dsk/c0d0s0 4205630 4146189 17385 100% /

I would go to the /var filesystem and start looking what you can remove. Look for large log files in /var/log that have been rolled up or compressed. You have /var/run on it's own partition, but not the entire /var fs, which kinda sucks for this very reason.

You have to be careful, but you have to find what to delete from /var. Perhaps you have a lot of old mail, or logs. I would definitely start in /var/log. Try this:
Code:
find /var/log -size +10000 -exec ls -lh {} \;

That should at least show you stuff that is around 1MB+.

would a file system being full (100%) effect mailx/sendmail??

---------- Post updated at 05:13 PM ---------- Previous update was at 05:09 PM ----------

The biggest file I have in my /var/log directory is 958KB
Next best place to delete things?

Yes. Sendmail write incoming and pending message into /var/spool/*. If can't write there, as evident by your sendmail errors in /var/adm/messages.

---------- Post updated at 04:16 PM ---------- Previous update was at 04:14 PM ----------

Code:
find /var -size +10000 -exec ls -lh {} \;

This will process everything in /var. BE CAREFUL!

Below is the listing of Items in /var
What do you suggest I take out?
I can always transfer them into my desktop for "back up" purposes

Code:
-rw-r--r--   1 root     other       8.5M Nov 30  2007 /var/sadm/install/contents
-rw-r--r--   1 root     other       8.7M Nov 30  2007 /var/sadm/install/t.contents
-rw-r--r--   1 root     root         12M Nov  9  2007 /var/sadm/wbem/logr/store
-rw-rw----   1 cvsroot  mail        1.2G Feb 17 02:10 /var/mail/cvsroot
-rw-r--r--   1 root     root        101M Mar 18  2008 /var/crash/tmusid01/vmcore.0
-rw-r--r--   1 root     root         89M Mar 18  2008 /var/crash/tmusid01/vmcore.1
-rw-r--r--   1 root     root        100M Mar 18  2008 /var/crash/tmusid01/vmcore.2
