Spam Blocking in Microsoft Outlook
Spam blocking in Microsoft Outlook is easy. Most parts of junk mail filtering are automatic as it comes as an embedded code in the Microsoft email client. You must have noticed that MS Outlook automatically handles most parts of junk filtering.
Because spam is a subset of junk mail, you can use the Junk Filter Dialog to filter out the unwanted mails. The Junk mail Filter Dialog offers you four options (see image below): a) No Automatic Filtering; b) Low; c) High; and d) Safe Lists only. To open Junk Mail Filter Dialog, right click on any message header and select Junk E-Mail -> Junk E-mail Options. You can also open the dialog from the Tools menu -> Options.
As evident from the label, if you select No Automatic Filtering, MS Outlook will let all mail into your Inbox without checking for spam. I suggest the default setting, Low. It may happen that you still get junk mail into your inbox with this setting. If you notice any junk/spam mail in your mailbox, right click on the message and select Add Sender to Blocked Senders List. Similarly, if you notice any useful email in the Junk folder, right click and select Add Sender to Safe Senders List.
When you select these options, you create lists of email addresses that are allowed/blocked. You can see the Safe Senders List and Blocked Senders List by opening the Junk E-mail Dialog and selecting the corresponding tabs (Ref Fig 1 above).
You can also block entire domains by using the International tab. This often helps in avoiding mails that originate from websites in different countries (as they may be in a different language). Click on the Blocked Top Level Domain List and select the top-level domains that you wish to block.
Tip: You can also use the Rules option under Tools menu for spam blocking in Microsoft Outlook.
