Like most people I have more than one email address, but unlike most I have them all pour into a single email address. This gets interesting with spam. A couple of my email addresses have made it onto the bulk mailing list, thus causing me to occasionally receive duplicate spam.

I go through my mail by hand. Fortunately I don't get a God load of spam each day, so it's manageable. I could use a filter, but I have yet to and would be curious to see if I miss anything. However, I would feel safe running a filter to clean my inbox of these duplicate spams.

So does anyone out there know of a filter that has the option "Delete emails from the same sender that have the same subject and possibly content"? Thunderbird support would be nice.
