Testuser_SST · January 6, 2012, 3:29pm

Hi,

when I try to start the postfix, the following messages is shown in the log:
Jan 6 16:22:13 maria postfix/master[2022]: fatal: bind 127.0.0.1 port 10026: Permission denied

and there is only a 100025 open.

Hi,

right, the selinux was still active, it works now. Should have been switched off already.

Thanks !

Kind Regards

Is SELinux enabled? (is by default enabled on CentOS 6). And if so are
you 100% certain that you created and installed the SELinux module to
allow Postfix to bind to port 10026?
