Hi Katherine,
I'm not really sure that I totally understood your original question -- I had just replied with what I do to deal with out-of-office replies, because we have a rule that allows any email subject line to create a ticket, but we didn't want tickets created for those automatic replies.
So to back up a bit, if you only want tickets to be created if the email subject line has this: "Incident - Sticker Tampering" -- then you should be able to just revise the rule that has this: [ \t\r\n]incident[ \t\r\n] to be this instead: [ \t\r\n]Incident - Sticker Tampering[ \t\r\n]
If that is the only rule that you have in the mailbox to create a ticket, then any other emails will be ignored.
Hope that helps.
Tammy
