There may be a lot of clogged mailers out there for those on library lists. Somehow, a previous digest for AUTOCAT (around 61Kb) got distributed as a message to the entire list. So, I expect that not only will that clog the systems, but the new digest may contain all of the previous digest, making it even larger. Unsuspecting subcribers (and listowners) may have problems as a result. I believe I know the source of the problem, but haven't figured out the cause yet. Now the "Help!" part. Our list is 100% open, despite having over 2500 subscribers, and we have never used the FILTER keyword. However, it looks to me like I can prevent a repetition by installing it. So, the question is this: will installing Filter= [log in to unmask] allow regular mail to go through but block weird loops? I don't want autocat@* as that would block some of the redistribution subscriptions from replying to the list (we have several set up that way). Sorry if I sound frantic, but I am. We get hundreds of errors per day and tomorrow I will be surprised if there is not a tidal wave of gribes about this, which will have to be dealt with also.
