[otrs] Customer name in salutation in wrong order

Hi all, We're running into a fairly minor cosmetic issue, and I'm kind of hoping that someone can help me out with it. Some of our customers have their names reversed when they send in email (ie instead of being from "John Doe" it comes in as being from "Doe, Jon"). If they don't exist as customers in the OTRS system (we're not currently using that functionality so pretty much everyone is affected) then when we reply, the default salutation is "Dear Doe Jon," instead of "Dear Jon Doe,". Is there any way to switch it around if the person's name has a comma in it? -- Chris Salter
