Some (or perhaps all) mail sent from our system to wnonline.net addresses is being rejected by the server at wnonline.net. We have reported this problem to them -more than once. If it is happening to you, please contact the person you are trying to write to at wnonline.net and ask them to report this. Perhaps if their paying customers ask they will realize that there is a problem. It has been reported to us that wnonline.net says this is our problem. However, the bounce messages clearly indicate that the mail is leaving our system and getting to the mail server at wnonline.net where it is being rejected.
If you have an 'in' at wnonline.net, please contact them and ask their help in resolving this. Since both ISP's are local, there are a lot of people who are being hindered by this.
While you are waiting, you may suggest to your friends at wnonline.net that they consider getting a free E-Mail account from Yahoo or HotMail or one of those services so that they can correspond with you. The only site which is rejecting our mail is wnonline.net so any other server will do. We, of course, continue to offer free E-Mail accounts to anyone with a library card.
Mail sent from wnonline.net is being accepted by our mail server so all of your incoming mail is getting through just fine.
