Postmaster check from email template

[ndhvu275]

Dear all,

I had a problem with checking template from incoming email by postmaster.
The template email have to check (have to exist key-words: 'Connection ID:', 'Netwerkeigenaar:', 'Aangemaakt door:')
Connection ID: ABC
Netwerkeigenaar: 123
Aangemaakt door: 3213123

I just know to check if matched then assign X-OTRS-Queue = postmaster, X-OTRS-State = new for example by check body of email as below
Body => ((.|\\n)*)Connection ID:((.|\\n)*)Netwerkeigenaar:((.|\\n)*)Aangemaakt door:((.|\\n)*)

But I dun know how to check for otherwise case, because I want to set X-OTRS-Ignore = yes for no match case

Please help me,
Thanks all
