Here are eight tips that can help you handle your email better and reduce the amount of spam and junk email you receive:
1. You can reduce junk email and spam dramatically simply by setting your "default" or "catch-all" email account to 'bounce default email' by configuring your mail server.
This will cause all email messages sent to addresses at your domain name that do not have a specific email box setup to be bounced instead of forwarded to one of your existing email boxes. This alone could prevent about 60-80% of junk emails from entering your domain.
2. If you do not check your email accounts regularly, spam and junk email can overflow your email account disk space limit and cause your email service to stop and not be able to receive any more legitimate emails.
To make sure that you are checking all your email accounts at the server, check your server mail folder and inside you will see files associated with each email account, if the size of the files are large, that means that there are emails in that account that need to be downloaded or deleted.
3. In the event that you setup an email account at your domain to forward to an outside email address, make sure to "unselect" the option to store email on the server in your mail manager, otherwise this will cause duplicate emails to be saved on the server causing your disk space usage to go up.
4. Install a server side spam filtering tool and use it properly to reduce spam and junk email. A spam filter can be a powerful tool provided that you configure and use it effectively. Ask y
