Hello, Many internet service providers have implemented spam blocking technology, such as Earthink.net's TotalAccess® 2003 with spamBlocker(sm) . Some of these technologies allow you to block all email except those addresses that are in your address book or in an "approved" list that you create. If you have this type of spam blocker, don't forget to include NYCATTAR-L@rootsweb.com or NYCATTAR-D@rootsweb as appropriate, in your "approved" list. Otherwise, after 3 bounces, our mailing program automatically "unsubscribes" undeliverable addresses. You may also want to include the list administrators address NYCATTAR@rochester.rr.com so that we can contact you if problems arise. Some other "Spam Eliminators" simply block email because the subject line looks suspicious. One of the tests many of them use is to look for subject lines, addresss or text containing text strings that aren't words. Unfortunately, NYCATTAR is one of those text strings many Spam Blockers don't recognize, and assume to be objectionable or offensive. How you deal with that would depend on your Spam Blocker or ISP. Thanks Dick Allen List Administrator - NYCATTAR
