When you send DBASE, LNK, and Lotus files as attachments via SMTP email,
the contents can be corrupted.

Note that Microsoft (MS) Access files (MDB) and MS Excel (XLS) files
do not show this same problem.

This corruption occurs because there is no default content type for
these type of files in the windows registry itself.

To circumvent the problem, in your code add the appropriate application
to open these type of files, for example, for Excel:

   attach=("file.dbf" ct="application/vnd.ms-excel")

For Lotus 123 you have

   attach=("file.123" ct="application/vnd.lotus-1-2-3")
