I currently receive emails every weekday from a service I subscribe to. These quickly clog up my inbox however, so I've decided that while the information I receive is important to my work, I only really need an update every two days.I therefore want to create a filter that sifts out emails received on a Monday, Wednesday or Friday, and deletes the rest.There is a header in each email mentioning today's date, but unfortunately filtering any message that contains Tuesday or Thursday results in a lot of false positives, as most of these emails also mention events happening on other days.A couple of inroads I can think of:Is there anything that can be done with the timestamps on each email?The format of the header date is, for example, Friday 08 March 2013. Is there any way to utilize this to distinguish it from the word Friday appearing in the text of the email, say?
