the dot in sender

Hello, I have a problem with sending the e-mail. Everything works fine, but when I trying to send e-mail with the dot in the sender field, the e-mail don't go out. Look at this:

    $From = "Sklep Orange pl  samsung-mobile pl <admin@samsung-mobile.pl>";

working fine

    $From = "Sklep Orange.pl  samsung-mobile.pl <admin@samsung-mobile.pl>";

dont working What's wrong?! This is the script:

    $subject = "temat test";

    $mailmsg = 'testowo';

    $From = "Sklep Orange.pl  samsung-mobile.pl <admin@samsung-mobile.pl>";

$To = $email;

    $recipients = $email;
    $headers["From"] = $From;
    $headers["To"] = $To;
    $headers["Subject"] = $subject;
    $headers["Reply-To"] = "admin@samsung-mobile.pl";
    $headers["Content-Type"] = "text/html; iso-8859-2";
    $headers["Return-path"] = "admin@samsung-mobile.pl";

    $smtpinfo["host"] = "----------";
    $smtpinfo["port"] = "25";
    $smtpinfo["auth"] = true;
    $smtpinfo["username"] = "----------";
    $smtpinfo["password"] = "------------";

    $mail_object =& Mail::factory("smtp", $smtpinfo);

    $mail_object->send($recipients, $headers, $mailmsg);
