ID: 26218 User updated by: bzheng at us dot nomura dot com Reported By: bzheng at us dot nomura dot com Status: Open Bug Type: Network related Operating System: W2k server/IIS 5/PHP in CGI mode PHP Version: 4.3.3 New Comment: just to clarify. The code is: $result = mail( "aa@aa.com", "sub", "msg"); Previous Comments: ------------------------------------------------------------------------ [2003-11-12 09:36:01] bzheng at us dot nomura dot com Description: ------------ calling mail() function causes PHP to send out an extra "RCPT TO: <>" command to the SMTP host. Packet sniffer shows: ... C:MAIL FROM:<some@somewhere.com> S:250 2.1.0 <some@somewhere.com> Sender OK C:RCPT TO:<aa@aa.com> S:250 2.1.5 <aa@aa.com> Recipient OK C:RCPT TO:<> S:553 5.0.0 <> User address required related entries in php.ini [mail function] ; For Win32 only. SMTP = mailhost.aa.com ; For Win32 only. sendmail_from = some@somewhere.com The weird thing is, the same code works on another machine that has exactly the same php.ini and php software as the machine having problems. Reproduce code: --------------- $result = mail( $t_recipient, "test", "test msg"); where $t_recipient is a valid SMTP email address. Expected result: ---------------- $result == true; Actual result: -------------- $result == false; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26218&edit=1
