This is nothing to do with PaX, as you can see from the log messages. |
| 35 |
Grsecurity is denying the execution attempt because you have |
| 36 |
TPE enabled and the qmail user is not trusted. |
| 37 |
|
| 38 |
See `Executable Protections' under Grsecurity in your kernel |
| 39 |
configuration, or `sysctl -a |grep tpe` if you have Grsec sysctl |
| 40 |
functionality enabled and unlocked. |
