Got it fixed! Simply solution. Just create a zfs file system for the pqueues with a modest amount of reservation size. I did 20Gb.

I'm trying to install postfix-2.7.2-RC2 on Solaris 10 sparc system.
Make and install goes through fine.  postfix starts up with no errors.
But getting the following errors in the log file:

Aug 10 09:58:43 mail1 postfix/smtpd[173]: [ID 947731 mail.crit] fatal:
statvfs .: Value too large for defined data type

this error  corresponds when a message is trying to be delivered.  The
sending mail server is getting a stat=deferred.

I've tried googling this error but not finding any solutions. One note,
the postfix install is on a ZFS file system.  Any idea why I'm getting
this error?
I speculate that the statvfs API can't handle the very large result
values that ZFS supports; perhaps Solaris has grown a new API that
Postfix currently isn't aware of?

A quick Google shows related issues in lots of software, example http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6433526 and documented here: http://docs.sun.com/app/docs/doc/820-4078/gdzmr?l=en&a=view#gevqm

Workaround: set quota or place queue on <2TB fs

Fix: use statvfs64
