Common Email Errors

Mailer daemon is the name of the mail server responsible for sending and receiving your email messages. If, for some reason, mailer daemon is unable to deliver an email message you have sent, i t will send you a message informing you that the message has not been sent and why it could not be delivered.

What do the mailer daemon's messages mean?

The message "Host unreachable - will resend message, User unknown" indicates either that:

• the email address of one or more recipients is incorrect, or
• the email server that you are trying to send mail to is currently out of service.

In most cases, the cause is an incor rect email address so review the original message and ensure all email addresses are correct.

What is a POP lock?

A POP lock is a mailbox lock. A POP lock error means that the mail server thinks that you are sti ll connected to the server so it will not allow you to make any further connections to it.

This error usually occurs if you have not disconnected properly from a previous session, for example if you turned your modem off before disconnecting from the server, or if your connection drops out while you are retrieving your email from the server.

Usually the mailbox lock will be removed if you wait about half an hour.

< FONT SIZE=+2>Common News Errors

For security, the news server is given a list of IP addresses (definition) from which it can accept news requests. When you dial in to your account you are allocated an IP address from this pool at random. Unfortunately sometime the IP addresses in the dial-up pool become changed or lost so are not recognised by the news server. If this occurs, you will not be able to read news and receive this error message.

Please log out the log back in to your account. You will receive a different IP number from the pool which should be recognised by the news server.

Common Web Errors

These puzzle pieces ar e displayed in the place of a graphic which your browser has not been able to load. There are several possible reasons why this might occur:

• You may have the Auto Load Images option turned off in Netscape Navigator. To turn it back on ag ain, from the Options menu select Auto Load Images so a tick is displayed beside it.
• The page may have downloaded incompletely or have been interrupted. Click once on the Reload button to download the page again.
• The image may be missing f rom the originating web site itself. If this occurs unfortunately the only thing you can do is email the site administrator if an address is provided and let them know that images are broken in the page you are viewing and provides its URL.

This message usually indicates that special permissions apply to the page you are trying to view and you do not meet the requirements. For example, many companies have web pages t hat are designed for internal use only and so they are set to allow only computers directly connected to the organisation's network to access them.

However if this is a page you expect to be allowed to view, check that you have set the port number in your proxy setting to 8080. If it is set to 80 or any other number, you will receive Error 403. It is also possible that the site administrator has set the directory with incorrect permissions but this is something only the site administrator can fix.

What does Error 404 mean?

Error 404 occurs when the document or web page you requested does not exist.

First double-check the address (URL) you typed to ensure it is exactly correct. Just one full stop in the wrong place will make the address incorrect. If you are certain you are typing the correct address and continue to receive Error 404 it is possible that the page has been renamed, moved to another located or removed altogether by the site administr ator. You can try browsing through the site to find the information you need.

I can see the home page but cannot view anything else. Why has this happened?

This means your prox y settings are incorrect. Review the instructions provided for Using AAPT's Proxy to ensure you have the correct settings.
