I am looking for documentation that helps me to update this file.  I am getting "Out of Office: ..." emails show up in the forums.

No, I don't think it will accept wildcards. Also, the values must be case-sensitive.

Search the forums for the rules. I believe few of us listed additional rules somewhere. We requested Will to include those rules in the default rules.xml file but I don't think that ever happened.

Thanks for the reply. I searched the forums and the internet/Google and found almost zero. I found examples with MatchType=Exact and some without MatchType at all, but none of the examples were much different than the default rules.xml I have in my mc directory.

If you have anything you'd be willing to share, as guidance, I would appreciate it.

I have found that the rules are case-sensitive, as mentioned by Ben. I was hoping MatchType might offer some options around that to at least reduce the number of combinations...

Here is what support told me.  Hopefully this answer will be useful to someone else in these forums.

Yeah, I was wrong before about requiring case sensitivity.
