How can one intercept base64-encoded email spam messages?
How can one intercept base64-encoded email spam messages through the Preferences>Rules feature of Mail?
I received numerous rubbishy spam emails again this morning. Again, all in base64 format and all of basically the same layout. Indeed, several of the lines of the base64 code were the same in all email messages. Given that these same lines are used, can they, or one of them, not be intercepted with a rule? For example, the line
appears in every message.
If this is placed in a rule such as
Message content contains Pg0KPHRyPg0KPHRoIGhlaWdodD0iNzkiIHNjb3BlPSJjb2wiPkxvb2tpbmcgZm9yIGhvdCBnaXJs
would this not work? (It seems not to.)
Or must one somehow use the translated equivalent of the code, or some other method?
Thanks for taking the time to answer.
Indeed, the string that I presented as an example is shown in the raw source view, the normal Mail view showing a layout of variously styled text and images.
Mail Rules can search the body of messages through the "Message content" condition. The thing is, it doesn't seem to recognize Base64 content, either copied as a full line of Base64 code, or in its decoded format.
I agree that it is in some cases just as easy to simply delete the unwanted messages, but when a computer is also used by younger members of the family, one doesn't want them confronted with the rubbish that these spammers seem to delight in sending. Far better to get rid of the stuff before it can be displayed.
PS. For my clients who get really annoyed with spam that is not filtered by their ISP mail server I recommend moving to a free email service, such as Gmail or Outlook or Yahoo, either explicitly or via message forwarding, where the spam filters are being continuously tuned by thousands/millions of user interactions.
