For the record, we don't really know why people who have Yahoo email accounts have messages that are bouncing. It may have nothing to do with specific words in the message. With the huge amount of spam that is clogging the Internet, providers are always trying to find ways of eliminating it before it gets delivered. These methods have to be continually upgraded as the spammers find new ways of getting around them. Not all of the Yahoo accounts were disabled. Administrators only get notices of bounces after the bounce score reaches 5 which means we have no idea whether people on this list are getting all of the messages until they have missed quite a few. The message we got as the reason for the bounce that triggered the subscribers who were disabled was that there had been a complaint and that messages were temporarily blocked. It was a canned message so I'm not sure what it meant. Complaints by who and for what was not clear. In the past when we were on mcn.org I got a notice of all of the bounces. Yahoo had more bounces that some of the other providers but I don't know if that is still true. When Comcast rejected all the pbs list messages we later found out that Comcast was rejecting everything from ibiblio.org since one person on another list had complained that he or she was not unsubscribed from a list after requesting this to happen. PBS subscribers who contacted Comcast asking to get the pbs list messages were given different solutions by the different support members they talked to. I've looked at some of the Yahoo subscribers since all of this happened and there have been a few bounces since, but obviously some of the mail is getting through. So it does not seem that all message are being blocked so I think that each subscriber who is having a problem probably needs to contact their ISP provider for help. Mary Sue
