Hi,
I?m using your helo checks, but today I received some spam, but this time with a forged "FROM", (which exists but it?s not mine) as you can see in the email source, is there a way to check this and stop this kind of forgery ?
Thanks.

Not much you can do with forged from unless implement SPF. But it will create problem if you use it too strength. Try to increase the SA score for DRUGS_ANXIETY, DRUGS_ANXIETY_EREC,DRUGS_ANXIETY_OBFU,DRUGS_DIET,DRUGS_ERECTILE is another option.

Hi,
I have beem thinking about this and don?t know if I?ve explained well.
the FROM that they are sending is from a email from my domain, that?s why they are entering in my whistelist.
AS you can see from the source althought the return path is contact@natuurfoto.net the from is one email from my domain.

this last from is forged, does this change anything in the way to catch this ? maybe crossing information from the return path with the 'from', they should be the same, no ?

Thanks

I looked you mail header closely. Your spam scoes is a minus value as a result of USER_IN_WHITELIST. Usually it score -100 but it seems you change it value to -30. Nevertheless, remove your domain on the from whitelist should help.
