Is there any limit of the max. size a file in
/var/spool/mail
could take? ( I know that for ordinary file size even
for aix 4.3.3, it could reach 2G size)

We discovered that a user cannot receive new mails in his
mailbox when his size is 1073741173 bytes
The error in the syslog is
--------------------------------------
mailer=local, pri=44320, dsn=5.0.0,
stat=Insufficient permission
------------------------------------
But the mode of his /var/spool/mail/username
is okay, i.e. -rw-rw----
and the ownership are also okay. Why the error Insufficient permission?

One more hint is that the last modified date of
/var/spool/mail/username could be updated even the file size
remains as it was

try ulimit
could be a soft filesize limit per user
