Hi all

I have noticed an annoying problem regarding spam-address filtering.

If I'm not wrong, it seems that email address filtering is processed 
using the "from" email address extracted from the "Received:..." 
header tag.

If that assumption is right, if I put into the spam-address.tab file 
any email address simply picked up from the "From:" header tag, any 
message coming from this email address will be filtered really out 
_only_ if that specific address is exactly the same one that we can 
find inside the "Received:.." header string.

I try to be more clear :-)

I have received one message containing these header strings (real 
domains substituted):

- Received: from <- snipped out -> from 
<[EMAIL PROTECTED]>;
- From: zzzzzzz <[EMAIL PROTECTED]>

In that case, I had the "[EMAIL PROTECTED]" email address in my 
spam-address.tab, but that email passed the filter anyway

Many spammers do that: is there a way to both check the "Received:" 
and the "From:" email fields? it should be more restrictive.

I hope to have been clear enough...
Thank you in advance
