Hello all,
I use Postfix with mysql database for the users lookup. I have recently
found an information leak with the RCPT TO command.
Here is an example:

Also please give me some idea about postfix performance tuning.

As Jeroen Geilman pointed out, it is "cleanup_service_name" instead of
"cleanup_service".

With many ISPs providing generic PTR, reject_unknown_reverse_client_hostname

mapping = exists, BUT
