I have contacted Rootsweb and found my problem is not unique and maybe worst than originally thought. the following is a partial response to my query; > When a large ISP such as AOL bounces RootsWeb mail, SmartList would > only > > unsub one address at a time.

As you can see the larger the list the bigger the problem becomes. Should you suddenly stop receiving this list please check with me to ensure your not inadvertently tossed off the list. Sorry for the inconvenience and bare with me and we will make it through this. Danny Clemmer In memory of Milo
