1) The AIX quotactl subroutine is defined here(put it in the search box)

Partial cut and paste of it:

Description
The *quotactl* subroutine enables, disables, and manipulates disk
quotas for file systems on which quotas have been enabled.
On AIX, disk quotas are supported by the legacy Journaled File System
(JFS) and the enhanced Journaled File System (JFS2).
The /Cmd/ parameter is constructed through use of the
*QCMD(*/Qcmd/*,*/ type/*)* macro contained within the
*sys/fs/quota_common.h* file. The /Qcmd/ parameter specifies the quota
control command. The /type/ parameter specifies either user
(*USRQUOTA*) or group (*GRPQUOTA*) quota type.
The valid values for the /Cmd/ parameter in all supported file system
types sare:
*Q_QUOTAON*
Enables disk quotas for the file system specified by the /Path/
parameter. The /Addr/ parameter specifies a file from which to
take the quotas. The quota file must exist; it is normally created
with the *quotacheck*
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/topic/com.ibm.aix.cmds/doc/aixcmds4/quotacheck.htm#a84c12e
command. The /ID/ parameter is unused. Root user authority is
required to enable quotas. By specifying the new quota file path
in the /Addr/ parameter, the *quotactl* command can also be used
to change the quota file that is being used without first
disabling disk quotas.
*Q_QUOTAOFF*
Disables disk quotas for the file system specified by the /Path/
parameter. The /Addr/ and /ID/ arguments are unused. Root user
authority is required to disable quotas.
Additional JFS specific values for the /Cmd/ parameter are as follows:
*Q_GETQUOTA*
Gets disk quota limits and current usage for a user or group
specified by the /ID/ parameter. The /Addr/ parameter points to a
*dqblk* buffer to hold the returned information. The *dqblk*
structure is defined in the *jfs/quota.h* file. Root user
authority is required if the /ID/ value is not the current ID of
the caller.
Did the trace hold any more information? Note that I didn't attach it
the first time I sent it to you, the second time I did. I also resent
the note with the trace attached to mailing list, but the mailman
software said it was too big, so I canceled the second post.
2) No, nothing is remote here:
1) dovecot is running here on mercury
2) mercury is where all the inboxes and home/folder dirs physically reside
3) These /are/ exported to other machines by mercury.
4) The quotaing is running on here mercury itself as part of O/S and
FSes; it is enabled during boot
5) rquotad runs to provide quota info to the remote machines where the
inboxes and home/folder dirs are NFS client imported and mounted

So apparently this quotactl() call is wrong with AIX:
if (quotactl(root-mount-mount_path, QCMD(Q_GETQUOTA, USRQUOTA),
root-uid, (void *)dqblk) 0) {
I don't know why though. You could try changing root-mount-mount_path
to some actual mbox file path to see if it returns errors then.
Except weren't your mailboxes NFS mounted? quotactl() doesn't work for
NFS mounts at all. For NFS you could try this instead
