Hello Friend,
When I try to login into my account it shows mailbox ...
I am using cpanel webmail program ..inwhich I use neomail..
When I click to Neomail it goes to Inbox..but dosn't show mail messages..
When I tried to fetch new mails it showed the error:

Neomail Error:
Your request didn't contain the proper session ID cookie -- access denied!

Can anyong know what is this?
I get thos mails on horde correctly..but not on neomail..
Thank you
