Q. How to block and prevent junk mail.
A
 
Q:How do I block e-mail not addressed to me using Outlook Express?
A: A common property of junk e-mail is that the intended recipient (the ¡§To¡¨ person) is often not you, the actual recipient. These e-mail addresses are often created by junk-mailers and are usually fake addresses or phony mailboxes.
   
  Outlook Express has a feature called ¡§Message Rules¡¨ which allows you to filter your e-mail by specific fields, such as ¡§From¡¨ or ¡§To¡¨ or ¡§Subject¡¨. So for junk e-mail which is not addressed specifically to you, Outlook Express ¡§Message Rules¡¨ can be used to filter out these junk e-mails.
   
  This can be done by specifying, using ¡§Message Rules¡¨ that only e-mails that contain your e-mail address in the ¡§To¡¨ or ¡§CC¡¨ fields be delivered to your Inbox. The junk e-mails that are not addressed to you can be left on the e-mail server deleted or delivered directly to your Trash.
   
 
1. Open the Outlook Express program¡Ago to [Tools]->¡uMessage Rules->¡uMail¡v¡C
   
2. Select [Where the To or CC line contains:] from ¡§Conditions¡¨
   
3. Select [Delete it from the server] from the second set of choices, ¡§Actions¡¨.
   
4. From the third set of choices, click on the blue underlined words and enter the e-mail addresses which you like to be affected by these rules. If you have more than one e-mail address that you use with Outlook Express, be sure to enter it as well. The addresses that you have specified here will no longer receive e-mail not directly addressed to them.
   
5. Select [Options].
   
6. Choose [Message does not contain the people below]. Choose [Ok]. Choose [Ok] again to return to the Message Rules window.
   
7. Choose a name for this ¡§Message Rule¡¨ for reference. Choose [Ok].
   
  If you have more than one Message Rule, please select [Move Up] to put this Message Rule at the top of the rule list. Select [Ok] to finish.
   
  Notes¡G
  If you have subscribed to electronic mailing lists, you may not receive your mailing list messages due to the above rules. To receive all your mailing list messages, make sure to add the recipient address for all your mailing lists when you are adding e-mail addresses in Step 5 above.

Q: What is spam mail¡H
A: Spam mail is a term for mail that is unsolicited, contains repetitive content, and sent to multiple recipients at once. Spam mail usually has nothing to do with the recipient and is sent randomly. Not only does spam mail cause undue network traffic due to its bulk nature, but it also costs customers time and money, from the time and effort taken to receive, read and delete spam mail.
The following two terms are similar to spam mail¡G
UCE = Unsolicited Commercial E-mail
UBE = Unsolicited Bulk E-mail

Q: How do the companies who send this spam mail know my e-mail address?
A:
1. Self-collecting
  Because many people on the Internet have their own webpages, and they often post their own e-mail addresses on their webpages, some e-mail addresses are obtained by people who browse these websites and collect e-mail addresses. Another possibility is that when posting to newsgroups using Usenet or Netnews, an e-mail address is required, and unscrupulous users can collect e-mail addresses from these activities as well.
   
This process of collecting e-mail is often done by scripts or programs, and is very hard to prevent.
   
2. Public collection
  When you are signing up for information, or buying products online, almost always you will asked to enter your e-mail address. Occasionally companies who collect information from the public will make their databases available for sale, and these databases are often purchased by e-mail spammers.
   
3. Occasionally, e-mail addresses will be collected illegally, whether through hacking or through taking advantage of security leaks. This, of course, is unlawful, but it still occurs occasionally.
   
 
Q: Are there any laws against sending junk e-mails¡H
A:
Taiwanese Internet Service Providers all follow the same guidelines about junk e-mail. If a user is found to be distributing unsolicited bulk e-mail, their Internet Usage rights will be disabled and said user will be unable to send any more e-mail. Often, these users will attempt to avoid detection by using fake e-mail addresses or creating their own mail servers.

Q: Help! My server/host has been hijacked and is being used to relay spam mail. What can I do?
A:
1. Most servers/hosts do not need to run a mail server. If you do not explicity need a mail server, disable and stop the mail server service.
   
2. If you really do need a standalone mail server make sure to add anti-relaying capability to your server software. Most recent mail server software, such as sendmail 8.9(+), already contains anti-relaying capabilities.
   
3. If you have domain zone control, or you are running a slave/secondary DNS server¡Ayou can control how internet traffic is resolved by using tools such as zone transfer and BIND. To learn more, read BIND documentation or visit the websites listed below.
   
4. http://dnsrd.nctu.edu.tw/Named-Conf/named.conf-s

5. As in Step 1, you can restructure your e-mail server and MX RR(Mail eXchange Resource Record) to prevent your e-mail server from being abused. Make sure that your mail entry and mail server configuration is correct to maintain security and consistency.
   
 
Q: I have a UNIX Mail server. How do I discover if or prevent my mail server from being used as a spam relay¡H
A:
1. If you are using sendmail 8.8.x or earlier, please upgrade your version to 8.9 or newer, because the 8.9 (and newer) versions of sendmail have built-in anti-relaying capabilities.
   
2. If you do not wish to upgrade sendmail 8.8.x to a newer version of sendmail, you can go to the following website to add anti-relaying capability to your version of sendmail.
