ec_rand — generate a random number no larger than max -1 or a random string from a list.
Synopsis
ec_rand { max/list }
Description
ec_rand returns a random number no larger than max - 1. It returns a random string from a stringlist.
If you wished to allow 90% of messages and fail 10% of the messages without differentiating between the messages themselves, we could use ec_rand to do so as below:
$num = ec_rand 10; if ec_test :is $num "0" { ec_action 421 "Service not available."; }
If you wished to log a random reason for your mail to be failed in the paniclog.
$reason = ["Service not available.", "Bad mailfrom.", "Malformed EHLO."];
$r = ec_rand $reason;
ec_log "${r}";
