Mike:
It makes sense, and I suspect my RT2 was vulnerable to this sort of thing.
But I've run it since 2001 and never had this happen. But I can see how it
could. I would imagine people with evil "out of office" responders would/could
create tickets as well, but I think most mail servers (even Exchange) is smart
enough to only send 1 "out of office" message.
So, what does RT do with the email/ticket if it matches? Does it get
silently dropped?
Also, I ~thought~ sendmail/postfix was smart enough to kill loops (or prevent
them from starting) based on the information in the email header. Apparently
not the case? If RT doesn't retain any of that information, sendmail/postfix
might see it as a new message every time..
