Bug #15590 Updated: PEAR's send() & special characters

ID: 15590 Updated by: mville@utc.fr Reported By: bjorn@swift.st Status: Open Bug Type: PEAR related Operating System: FreeBSD 4.5-REL PHP Version: 4.1.1 New Comment: This problem is still present in the 4.1.2 version of PHP/PEAR. It can be reproduced using IMP 3.0 as MUA and Postfix as MTA. Postfix users can use this workaround : you can add the 'reject_non_fqdn_recipient' to the 'smtpd_recipient_restrictions' postfix parameter to reject the badly RFC822 formed email containing the '<@>' recipient address. Then, the email client (IMP 3.0) will display an error message. Additionaly, if you have your MUA (IMP 3.0) and your MTA (postfix) on the same host, you must configure the following Horde 2.0 parameters(located in the 'config/horde.php' file) : $conf['mailer']['type'] = 'smtp'; $conf['mailer']['params'] = array('host' => 'localhost'); Previous Comments: ------------------------------------------------------------------------ [2002-02-17 00:18:50] bjorn@swift.st When sending mail to an email address including special characters (i.e. æáó) using PEAR's Mail send(), an error is not returned but an email sent to the local postmaster account. While the following command sends an email to "ævar@example.com" (and allows the MTA to do the error handling) <?php mail("ævar@example.com", "Test 1", "Using mail()") ?> .. the following example code (taken from http://pear.php.net) sends an error to the local postmaster account. <?php include('Mail.php'); $recipients = 'ævar@example.com'; $headers['From'] = 'me@myhost.com'; $headers['To'] = $recipients ; $headers['Subject'] = 'Test 2'; $body = 'Using PEAR\'s send()'; $params['sendmail_path'] = '/usr/local/sbin/sendmail'; // Create the mail object using the Mail::factory method $mail_object =& Mail::factory('sendmail', $params); $mail_object->send($recipients, $headers, $body); ?> I have played a little with the PEAR code and traced the problem to a regular expression match in Mail/RFC822.php, line 518. if (!preg_match('/^[\\x00-\\x7E]+$/i', $atom, $matches)) { return false; } I have red *some* of RFC822 and know that ASCII characters above 127 are not allowed (correct ?), but shouldn't PEAR either a) Return an error b) Pass the message along to the MTA like mail() .. instead of the message going to the local postmaster without notifying the sender ? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15590&edit=1
