Product managing the service: Select which of the applications will run the service.For
PrintShop Mail Connect the Designer is the only choice.
Note
The Server Engine is set as the default as it is generally considered the best
option.
This is particularly the case when using a scheduled cron job, as the Sever Engine
is always running, whilst the Designer might well not be at the scheduled time (in
which case the clean-up will fail to run).

l
Allow database clean-up service: Select this checkbox to enable the database
Clean-up settings, and enable the actual clean-up.
l
Threads to use for database deletions: The number of Threads to be used
in the clean-up. PrintShop Mail Connect is a multi-threaded application, and
the clean-up is likewise.
Tip
The default number of threads is considered the best compromise for
running both clean-up and production jobs simultaneously. If experience
suggests that the clean-up is not running efficiently, then upping the
number of threads here would be recommended. Conversely, if
production appears to be suffering courtesy of the clean-up process,
then reduce the number of threads here.
In general, higher end machines (those with multiple cores) will allow a
higher numbers of threads, whilst low end machines will perform better
with a lower number of threads.
