Read, unread & delete option not working in Postfix
 

I am using Postfix mail server. I can read and send mail from webmail perfectly. But can not delete mail from webmail as well as read & unread option not working.

Oh, we are using squirrelmail as webmail. Every user can delete mail but i can not delete.

Another matter is that i can delete mail from trush folder.
When i try to delete the below message show:

Please help...

Hi,
It's not postfix but squirrelmail that gives this error.
Check the webserver logs, to see if you find anything unusual.

Regards
