The following FAQ is related to send and receive mail.

** How long should I set my mail program to read the mail like in Netscape ?

We recommend to set it to 0. In the Netscape, it was default to have in every 10 minutes, however, you have to check if this is practical for you. If you are only getting one or two mail in a week or a day, there is no point for you to go to the post office (mail server) to check out if you have mail in every few minutes. We recommend to set it to 0, which means you manually click to check mail when you want to. It would be better just to have the habit to check your mail first when you get on-line, and may be check one more time before you sign off.

** If I get a lot of mail, do I set it to check mail in every 1 minute or two minutes so that I can retrieve mail more often?

No, If you know you are only getting very short mail, this might work, however, if your mail is larger than your modem can transfer in that time period, your mail reader will send second request to transfer you mail before the previous one finish downloading your mail in the mail box. If your mail is not fully downloaded, it will not be erased from the server, and the second request will download the same mail again and again and again since the 3rd request will kick on before the 2nd one finish its downloading. In this situation, you will see all the repeating mail coming in again every time you retrieve the mail. In that situation, you must set the time longer or set it to manually retrieve the mail.

** I kept on repeatedly getting the same mail every time when I checked for new mail. Why?

This kind of problem would happened more often when you have more messages in the mailbox. If there is 1M of mail, it would need about 6 minutes or longer to download the existing mail. But if you access the mail server every 5 minutes, the second process would start downloading the mail before the first one finish all the existing mail and clean up the mail box. Your mail reader will start to download the same mail again and again and again (since the 3rd process kicks on before the 2nd one ends) and you will "see" the computer getting 'stuck' but actually still downloading.
Besides, you also have to make sure in the mail reader, the field "Remove mail from server after read " had been checked. This would ensure the program to remove mail from server after you had read it.

**I kept on getting mail from Mail delivery subsystem at: mailer-daemon@mailhost.cin.net, and even I ask them to quit flooding me with tons of copies of the same returned mail. Why no one stop it?

Before you start complaining others, please READ those message carefully. Those usually are the warning message like "user unknown", "mail not delivery in 4 hours due to no route to remote host" ...etc. These message are generated automatically by the mail system , not any human. Do not send mail to those e-mail address, or you will get all of them bounced back to you. To avoid these problem, read the message carefully, and solve the problem accordingly. If the message says "user un-known", do not send any more mail to the same address before you double check it and make sure that is the right one.

**I can send mail out, but any one try to response to my mail will get a "user unknown" error message and mail bounced back to the sender, why ?

In the mail program, make sure you have your e-mail address and return address correctly entered. If the field in the mail program only ask for username, do not put your e-mail address there but just the username.
