Note Submitter: chrisg at cordell dot com dot au ---- When adding attachments to the message body on a Windows system, always open the file using the binary flag option i.e. fopen("filename","rb"). If you don't then any non text attachments will be unreadable when the email is received. The binary flag is ignored if not required so it does no harm to always include it in these circumstances.
