Max. Postmaster email

OTRS is able to send automatically email replay. So it's possibe to create an email loop (of course we check bulk headers but other some strange systems not!).

Example 7-5. Kernel/Config.pm - PostmasterMaxEmails

[...]
    # PostmasterMaxEmails
    # (Max post master daemon email to own email-address a day.
    # Loop-Protection!) [default: 40]
    $Self->{PostmasterMaxEmails} = 40;
