When closing a ticket from no reply it creates a new ticket

Hi guys

we have some external services who creates a ticket.

when we add comments  or close  the no reply address doesnt alow to be mail send at.

so we get a nondeliverable from our mail server.

wich creates a new ticket.

to skip^the sending mail if assigned or comment are added we can solve this.

Any ideas ? 

We have 5 or 6 mail addresses who send mail from noreply.

so every time we close a ticket it try to send to the address which then creates a new ticket cause we cant send to this address.

In our previous servicedeqsk system we had a mute button once clicked it didnt send any messages.

so when we made a rule then from mail adress -mute it worked.

Kind Regards,

David
