CWP Panel not opening after reboot

Hi,

Outgoing emails where sent successfully but was not delivering to the receiptant. Incoming emails are working fine.
To resolve this outgoing email issue i rebuild mail services and then took a reboot from the CWP panel.

But After doing the Reboot from CWP panel, the CWP panel is not opening from anywhere.

First I was having outgoing emails issue but now I have CWP panel issue as well

If anyone have idea for same then please do help.

Hi,

I fired below command using SSH and the panel started working

yum -y update

But my emails are still stuck in the Mail que.

you should add more information, By saying "But my emails are still stuck in the Mail que." its means nothing for us.

Sure,

PFB the details about the exact issue of email.

My emails are being sent from outlook and roundcube but they are not delivering. I checked they are stuck in Mail Queue and I am unable to understand why it is happening. 

Note: I am able to receive emails
