Sending two attachments

Hello, I am trying to send multiple attachments by email from my PHP program (two to be precise). I have put the relevant codes to send attachments, and separated it with the Message Boundary. The first attachment comes fine. The second attachment is also coming to my Inbox, but for some reason, Outlook Express (my mail client) does not recognize the 2nd attachment. The message header and the size of the email indicates that the content has two attachments. Any clues? The email looks like this after the standard headers for From and To: MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="Message-Boundary" This is a MIME encoded message. --Message-Boundary Content-Type: text/plain; charset="iso-8859-1" Testing mail component --Message-Boundary Content-Type: application/octet-stream; name="ValleyView1.csv" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="ValleyView1.csv" Um9vbUlkLFNlcmlhbE51bWJlcixEaXNwbGF5T3JkZXIsRGVzY3JpcHRpb24sUmF0ZVR5cGUsQWR1 bHRQcmljZSxDaGlsZFByaWNlLE51bURheXMsTWluUGVyc29ucyxNYXhQZXJzb25zLEFwcGxpY2Fi bGVEYXlzClIwMDIsMiwxLERvdWJsZSAzIG5pZ2h0cyxWQUwsMjI1LjAwLDAuMDAsMywxLDIsIjAs MSwyIgpSMDAyLDEsMixEb3VibGUgNCBuaWdodHMsVkFMLDI4MC4wMCwwLjAwLDQsMSwyLCIwLDEi Cg== --Message-Boundary-- Content-Type: application/octet-stream; name="junk.txt" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="junk.txt" SnVuayBUZXh0IEZpbGUKTGluZTIKTGluZTMK --Message-Boundary--
