Applications that send mail normally have some configurable options.
You might have the option of handing to sendmail (or the replacement
program mailer the postfix provides) over a pipe or you may be able to
configure sending via smtp. In the latter case, you can probably
configure a relay host if one already exists for handling mail in the
organization instead of running postfix locally as the relay. If you
do have to run your own postfix instance, then it must either relay
through a well-managed system or have a lot of things configured
correctly so it can reach the recipients and will pass their spam
checks.
