With a gmail account your life can become a lot easier... You make your rules and your mail gets cleaned of junk relatively easy. But what if we get a spammer that decides to send his mail via something else? This mail is called the via spam. Sadly enough google can not filter these mails out with their rules.
Do you have a regular load of spammers in your spam box? Well you can automatically clear them out.
Are your rules not catching a via spam? Well you can actually clear those out too.
All thanks to the totally great google apps.
All you need to do is add this script. You can do that by going to your google drive, in your My Drive right click and choose new file. Then choose google apps script and you are done. Just copy this code over what is given and save it under a name. You will see a little clock with a popup 'current program triggers' which you can use to setup a daily (which should suffice) trigger to walk through your spam box and basically delete all spam from which you know it is really junk spam. This way the other spam (which may inadvertently hold mail that are not spam) gets automatically deleted. Thanks google... :)
