Hi guys I'm trying to connect to an imap mail server using zend frameworks Zend_Mail_Storage_Imap function. Its working with some accounts but with most accounts it just dies out. I'm connecting using:

$mail = new Zend_Mail_Storage_Imap(array('host' =>$current_dept->incoming_server,
'ssl' =>$current_dept->ssl,
'port'=>$current_dept->incoming_port,
'folder'=>$mbox_name,
'user' =>$current_dept->email,
'password' =>$current_dept->email_psd));

WIth some email accounts teh code doesn't go past this statement - and instead I'm prompted to 'download' the php file being run. Whats happening here - the mail server details are correct.
