Did you use the su - zimbra? Not su zimbra, without the less simbol, is important to execute su - zimbra and then zmcontrol restart.
So, please try this workaround:
su - zimbra
zmcontrol stop
exit
/opt/zimbra/libexec/zmfixperms --verbose --extended
su - zimbra
zmcontrol start
zmcontrol status
Do you have SElinux active?
Best regards

Hi Damanmokha,
Can you please capture /var/log/zimbra.log file error during restarting zimbra services (# zmcontrol restart)
and send us Error text file.

AUTORELABEL=0|1[/quote]That output show that SElinux is in permissive mode not disabled, you should disable it. The initial output indicates you have a DNS problem and the output of your host file shows that the entry for you server is incorrect. I'd suggest you read the Split DNS article again (the link has already been provided earlier) and modify your hosts file. WHen you've made the modification to your hosts file and fully disabled SElinux you should run all the commands in the 'Verify......' section of the Split DNS article to confirm your configuration is correct. Do you also have a firewall on this server? If you do, do you actually have a DNS server configured behind this firewall?
I'd also suggest you have a problem with your external DNS records, this is the output of a ping:
ping mail.askcentos.com

You can also use one of the many internet sites that check and diagnose DNS problems, see what they have to say about your records.
