Good morning, sir:

I get this error message when I attempt to open a IMAP conection:

Warning: Couldn't open stream {localhost:143} in /var/www/html/prueba.php on line 2

This is the code line that I use; "ruclamo" is my valid system user and "123" is  my password :

<?
	$mbox=imap_open("{localhost:143}", "ruclamo" , "123");
?>

I used this code on Red Hat 7.2, with nothing problem.  Actually, I am working with Red Hat 7.3,  with all php and imap packages installed.

Thank you, excuse my poor English,

Ruth Moreno
