You have a mail application that does the job for you with the exception that junk mail filtering to a separate folder is not working. I don't think its time to switch applications. Better to concentrate on fixing the problem with your existing application.

There is usually 2 stages to Spam filtering, firstly it gets marked as Spam, secondly get moved to the folder. Are the messages being marked as Spam, this could be something really obvious in the subject or it could be hidden in the headers.

If it is being marked then try changing the setting for moving the spam to a folder, a different folder perhaps and see if this kicks it into action.

It the spam isn't being marked then try changing the filter settings, set them all off, restart the mail application and then set them how you want them.

We must be able to kick this back into action.

My record for spam was 3,000 a day and that was every day for a few months, currently 90 a day.

Tom - I wouldn't recommend connecting any computer directly to the internet without a firewall installed and switched on. Fortunately for the Mac it has a firewall and you can't switch it off and it automatically does a good job of keeping only what is absolutely necessary open to the outside world. I always recommend 2 lines of defence and connect via a router as the 2nd line.
