For ISPs, it's important to make sure that abuse@ and similar NOC addresses don't block incoming mail. (Similarly, spam filters can make it difficult to submit spam complaints...)
Its easier said than done. Unfortunately, there are DOS attacks on ISP abuse@ (and other well known addresses) in progress. Perhaps all ISPs should always have enough capacity to handle an infinite number of messages to any contact; but reality sometimes intrudes. I don't know a good answer to the problem. You don't want filters on your Abuse contact, but then it gets abused. As a general policy the best I've come up with is Abuse should not be included in the "standard" corporate or ISP filters/blocks. However, Abuse may have separate filters to deal with abuse specifically directed at Abuse.
