Hello there,

I have a script which logs in to imap email account and processed that script.
Today that script suddenly stopped working.
I may have done php upgrade on my system
I'm using fedora 18 64 bit with php version

PHP 5.4.20 (cli) (built: Sep 19 2013 09:03:36)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

When I run that php page from browser it fails to function imap_open with following error

Warning: imap_open(): Couldn't open stream {mail_server_address/novalidate-cert/imap/ssl}INBOX in /var/www/html/test.php on line 6
Could not Connect to MailServer mail_server_address
Notice: Unknown: No such host as mail_server_address (errflg=2) in Unknown on line 0

but strange enough when i run this script from command line like
php -f test.php
it works.

My web server runs as apache user.
I can run script as any user and it works fine from command line
but it fails from browser.
Can anyone suggest me what could be the issue?
