Silent Resolve (MuteResolve ReRedux)

I couldn't get either the MuteResolve or MuteResolve Redux solutions to work, so here's mine. It seems to work well and is simpler. Tested with RT 4.0.2, but sould probably work with 3.x versions as well.

1. Create a Ticket Custom Field called Silent Resolve. (Tools->Configuration->Custom Fields->Create) Name: SilentResolve
   Type: Select one value
   Render Type: List (you may have to save it before this option appears)
   Values: Sort=0, Name='Yes'
2. Select it under Tools->Configuration->Global->Custom Fields->Tickets. (Why the two-step process beats me, especially when they have an Enabled checkbox on the field definition in step 1)
3. Create a new Global Template (Your mail server should route nobody@ to /dev/null)
   Name: Resolved (Check Silent)
   Type: Perl
   Content:
   

     { 
     $nobody = 'nobody@localhost';
     if ($Ticket->FirstCustomFieldValue('SilentResolve') eq 'Yes') {
     "To: $nobody\nCc: $nobody\nBcc: $nobody\n";
     } else {
     ;
     }
     }Subject: Resolved: {$Ticket->Subject} 
    
     According to our records, your request has been resolved. If you have any
     further questions or concerns, please respond to this message.
     

Note that the "}Subject" is not a typo. You need it like that to make sure all that stuff is part of the e-mail header.

1. Set the "On Resolve Notify Requestors" scrip to use this template.
2. Create a new scrip. (Tools->Configuration->Global->Scrips->Select)
   Name: Unset Silent Resolve
   Condition: On Reopen
   Action: User Defined
   Template: Global template: Blank
   Stage: TransactionCreate
   Custom Condition:
   

 return ($self->TicketObj->FirstCustomFieldValue('SilentResolve') eq 'Yes' ? 1 : 0);
 

Custom action preparation code:

  $self->TicketObj->DeleteCustomFieldValue( Field => 'SilentResolve', Value => 'Yes');
  $RT::Logger->info("Silent Resolve unset on Reopen of ticket ".$self->TicketObj->id);
  return 1;
