Been a spamgourmet user for a long time. It's awesome.
It's very flexible in naming conventions, number of nuisance emails it will let through, and also as a disposable email generator.
(For instance, I sign up for stuff and use the website or offer as my address - so, for example '
[email protected]'... That way, I can actually pay attention to who is sending my name, where. And you can adjust it to allow one message through - a confirmation, say - or up to 20 messages through. And while it doesn't archive messages, it does keep a count of how many it's thrown away over the years, from each address...)
