Sending Mail to a Ticked create a new Ticket (did not add in existing ticket)

Sending Mail to a Ticked create a new Ticket (did not add in existing ticket)

Hello,

the whole day, some to our Desk mailadress sended Mails generate a new Ticket instead of adding the Mail to the existing Ticket.

I've made several test for that. normaly the Mail where added into a ticket if we add "[##tickeid##]" in the Subject of the Mail (tickeid is the uniqe ticket number) to send it to a specific Ticket, nothing else.

My test below show, that the Ticket Name (or Mail Subjact) now is a value to add it in a ticket too:
My test Subject.                                                         New Ticket generated?
Aw: [## 12629 ##]  Test                                             no
Aw:[## 12629 ##] Test                                               no
Aw:[## 12629 ##] 2Test                                             no
Aw:[## 12629 ##]Suppe                                            YES
Aw:[## 12629 ##] suppe Test suppe2                       YES
Aw:[## 12629 ##] wah Test                                       no

My ticket is called "Test".
You see, that the subject are scanned to. Is this a new feature (we dont need that, can we deactivate it) or a Bug?? Please we need fast help, this bug generate today 50 wrong tickets in our system...


Thank you!!

Kind regards,
Klaus Brandt
