Default Errormessage in maillog - empty query string

I have found following errormessage in my maillog:
postfix/smtpd[36719]: warning: table "mysql:/etc/postfix/mysql-virtual_client.cf": empty query string -- ignored
System is ISPConfig3 on CentOS6.0 installed according to the perfect server guide. The error occurs everytime mail is sent from PHP app on localhost (and not for other mails).

I have found the same issue in this thread:
It is 5 year old and have no conclusion, so I thought to ask again.

My mysql-virtual_client.cf contains this:
user = ispconfig
password = password
dbname = dbispconfig
table        = mail_access
select_field = access
where_field  = source
additional_conditions = and type = 'client' and active = 'y'
hosts =
I'm not sure whether there is something wrong or it is normal - the mails seems to be delivered correctly. But I would like to know the reason for the message to be sure.

Thanks in advance for your help.
