Dear Jeroen, Dear Viktor, If I put "grey0 = dunno", when this value is used, Postfix return a Warning on le logfiles.
The rules from Viktor work "grey0 = check_client_access static:dunno" work. Postfix understand the value and don't give a warning on the logfiles. With my other script and the problem "command time limit exceeded", I've update again the value "sendercheck_time_limit" to 7200 ... Since today, I don't have see the error on the log file. I would say thank to Wietse, Jeroen and Viktor for the contributions and all others that they have read me. Bests Regards, Damien
