There is a bug in imap_connect(), it requests a SSL certificate, even when not told to do so.

the code I use is:

    $host = "localhost:143";
    $mbox = @imap_open("{".$host."}INBOX",$user,$pass);
    if(!$mbox)
    {
        echo "error!!<br />n";
        echo imap_last_error();
        die();
    }

the error message is:

Certificate failure for localhost: unable to get local issuer certificate: /C=...

I'm using a self signed certificate for the IMAP SSL. But, the server I use in port 143 doesn't use SSL. (SSL IMAP is on port 993)

if i change the host line to:
    $host = "localhost:143/novalidate-cert";

it works.

It worked fine in 4.2.2, after the upgrade (4.2.3) the mail service was broken.
