[rancid] How to stop notifications for an ACL change on a Cisco ASA?

[D J]

I have a cisco ASA firewall which has an access-list that changes many times
a day programatically. I do not wish to receive e-mail notifications of
these changes, but don't mind (and would like) to log them into CVS if
possible. What is the best method to tell Rancid to not notify on a change
which contains a certain value -- like "access-list 1234"?

Thanks!
