[X4U] Why is email filtered to trash?

[Crandon David]

Hello Everyone,

OK, a weird thing just started occurring. I'm using 10.4 with Apple  
Mail.

Suddenly, I started having a few emails being filtered to my Trash  
folder when downloading them from the ISP's server.

At first, it was one particular guy, who has sent me emails before  
without a problem. Suddenly, his emails were filtered to my Trash  
folder, without me even looking at them.

Then, yesterday, one email from the list, got filtered to the trash  
as well.

I have no filters set up to do this, and these emails are not marked  
as Junk mail.

Anyone have any ideas?

I'd like to forward them to someone to see if it does it on anyone  
elses machine as well.

Thanks,

David
