It appears that SPAM is truly starting to show a surge when even the spam filtered mail still has a number of items that seem to get through. There are few things you can do. Obviously you shouldn't be opening any email that doesn't appear from someone you know. Unfortunately there are many ways spammers are now attempting to trick you. One way is to make it appear as though the message was actually from yourself. Think about it, if this is the case, obviously you are not going to create a rule to block that since it is yourself... And since more and more spam filter programs look out for these sort of rules, it appears that not all work and that is when you start picking up a lot of new spam issues. Keeping up to date with the spam DEFINITIONS become important. For those using Microsoft Outlook, this is a good time to make sure you have the latest spam filter definitions, something you can always check through the microsoft office update site.
For those of you that are using highspeed connections, this probably means your internet provider also has a spam filtering service built in to the email and this is important that you are forwarding this sort of spam to them to add to the blacklist. Check your internet providers home page for information on email filtering as most now do offer this. It won't block all spam but any little bit helps.
Another way to filter your mail even further would be to open up a web based email account such as Hotmail or Yahoo mail where you can then forward all of your email from your internet providers email account to this new email account where it will be filtered once again. Since you don't have to tell anybody this email address, you can use it as your filtering system. Only problem is that your email is now web-based and not something that is being downloaded as it is when using outlook/express. All this forwarding and filtering, just where is this leading us to next? This is one reason why I see learning how to send and forward email the correct way must start from you and then be promoted from within, otherwise we will continue to not even have a chance against the spammers trickery.
