From the Project/Properties menu, click on the
General tab:
The Description field may be used to enter a short description
about the project.
Select a Charset: this value is also set from the
mailing defaults box.
Select a default Language for contents. It is used by script
engine to format date, time, number, etc.
Select a Mail Datemethod: this value
specifies when the MIME header date & time should be
set.
Check the Render one mail per receiver option if your data
source has an email field including several addresses per
record value. A distinct email file will be rendered per each
address (this feature is not available for fax numbers).
Check the Do not render duplicates option to render only one email
or one fax per receiver having the same address. Using this option is an
alternative to using the Remove Duplicates tools.
Specify an Error ratio threshold to abort the render. Enter 0 to abort
the render at the first error. If the value is 100, the render will never abort.
