Problem in using php-imap in rh7.3

Hi all, I got a problem when I use php's imap functions in rh7.3 system. In the php script file imaptest.php I wrote such code: $user="usernamexxx"; $password="passxxx"; $mbox = imap_open ("{localhost:143}", $user, $password)

     or die("can't connect: ".imap_last_error()

But when I use konqueror visit it through http, the result shows: " Warning: Couldn't open stream {localhost:143} in /var/www/html/mail/imaptest.php on line 4 can't connect: Certificate failure for localhost: self signed certificate: /C=--/ST=SomeState/L=SomeCity/O=SomeOrganization/OU=SomeOrganizationalUnit/CN=localhost.localdomain/Email=root@localhost.localdomain " I found such words in the maillog: Jul 10 10:09:43 revived imapd[1465]: imap service init from 127.0.0.1 Jul 10 10:09:43 revived imapd[1465]: Command stream end of file, while reading line user=??? host=UNKNOWN I'm sure that my imap works well. Because I can use Kmail receive mails through my imap. Who can help me? Thank all. Best regard! Yours,
