As far as I can see todays spammers and hackers will get past almost any filter, but for what it is worth, the e-mail I have had for 10 years but nearly gave up on a couple of years back, freeuk.com , now does a pretty good job for you pouncing on any formulaic ones within a few hours. The web-mail is very fast and not an ad in sight, so can do final hand weed in a few secs then do a mailbox>get new mail>from command and then no junk gets to the computer in the first place. For servers that do not have a web-mail option, mail2web.com does the same job for any number of addresses, but not quite so fast.
