Not sure why you would think that it only applies to inlines. It's a
method for ModelAdmin (shared by InlineModelAdmin through inheritance).

>>> from django.contrib.admin import ModelAdmin
>>> ModelAdmin.get_fieldsets
<unbound method ModelAdmin.get_fieldsets>

Try this:

class MailboxAdmin(models.ModelAdmin) :
list_display = ('localpart', 'localdomainfk', 'type',
'aliastargetaddresses', 'created', 'updated')
fieldsets = [
(None, {
'fields': (('localpart', 'localdomainfk'), 'accountfk', 'lifetime',
'type')
}),
]

def fieldset_section(self, title, fields, classes=None) :
if classes is not None :
return (title, {
'fields': fields,
'classes': classes }
)
else :
return (title, {'fields': fields})

def get_fieldsets(self, request, obj=None) :
alias_classes = mailbox_classes = None
if obj :
if obj.type == 'A' :
alias_classes = ('collapse',)
elif obj.type == 'M' :
mailbox_classes = ('collapse',)
fs = self.declared_fieldsets
fs.append(self.fieldset_section('Mailbox',
('aoxuserid', 'quota'), mailbox_classes))
fs.append(self.fieldset_section('Aliases',
('aliastargetaddresses',), alias_classes))
fs.append(self.fieldset_section(None,
('remarks',)))
return fs
