For years I have been sending out a weekly newsletter that includes links to things like videos made by members of our group (these are for visual choreography learning, we are a singing group). All of a sudden how my e-mails are not going through. I checked at first with my ISP and they said that it is showing that Thunderbird indicates that they think my email is spam and is now blocking it. What can I do. There is nothing mean or morally corrupt with what I am trying to send. Some of the links are for things like google.docs and google photo apps. I had an earlier message that stated that the email was spam, but I did not get a copy of that, and now I am getting this message: Sending of the message failed. An error occurred while sending mail. The mail server responded: <END-OF-MESSAGE>: End-of-data rejected: user has temporarily exceeded the allowed mail recipient relays per day. Please try again later.. Please check the message and try again. Please help!
