Requirements

• many-to-one assignment (one assignment group can have many email addresses)
• should not have to edit code to add/update/delete queue mail aliases
• should ignore Cc: address list

Proposal

• create a related table under Assignment Groups for Mail Aliases
• modify the Create Incident inbound action script to use the new table to match To: address to Assignment Group

Steps

• create/populate table 'u_group_mail_aliases':
  • u_email (string)
  • u_group (reference to sys_user_group)
• update the Create Incident inbound action with something like this:

  // bw -- expose headers and text in description (just for PoC)
  // current.description = email.headers + email.body_text;
  
  // bw -- find assigment group by doing a lookup in u_group_mail_aliases
  // loop through email.direct 
  var addresses = email.direct.split(",");
  for (var i=0; i < addresses.length; i++) {
      var alias = new GlideRecord('u_group_mail_aliases');
      alias.addQuery('u_email', '=', addresses[i]);
      alias.query();
      if (alias.getRowCount() > 0) {
          break;
      }
  }
  // if there was an alias match, use it to assign group
  if (alias.getRowCount() > 0) {
  // first match wins!
      alias.next();
      current.assignment_group = alias.u_group;
  }
  

...the table can be permissioned as appropriate (probably fine to restrict it to admin). Might be nice to restrict the u_email field to be unique, but that's just icing since it's enforceable manually by any reasonable admin.

Configuring

The mail alias binding to groups happens at the Group level in Adminstration controls. Click a group, and then bottom of the dialogue page contains a tab called "Group Email Alias".

To configure a new alias, we need to open a ticket to YSS Client Accounts and make a request to bounce the mail to servicenow@yale.edu
