Attachment not sent with E-mail

I am using Universal Email 4 with pear mail using smtp. The emails are sending, but the attachment is not. I have configured email for attachments per instructions. I have searched forum with no luck. I am using my own web server which has windows 2008, iis7 with pear installed. I have the correct path to pear and mail and mime are installed. I am also using my own email server, which requires smtp authentication. In my php.ini file size limit is set to 100M and the timezone is set to America/New_York. When I complete the form, the errors displaying are timezone errors in the PEAR_Mail_using_SMTP_php.php file on line 183. Line 183 reads $headerArray["Date"] = date('r (T)'); . Another error is
We selected 'America/New_York' for '-4.0/DST' instead in C:\inetpub\LocalUser\jesse\contact.php on line 109 Warning: Cannot modify header information - headers already sent by (output started at C:\inetpub\LocalUser\jesse\webassist\email\PEAR_Mail_using_SMTP_php.php(258) : runtime-created function:1) in C:\inetpub\LocalUser\jesse\contact.php on line 109 - line 109 reads $this->Importance = ""; in addition to other errors. Any help would be appreciated.
