Max. Postmaster email

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

Example 6-5. Kernel/Config.pm - PostmasterMaxEmails

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