help about whitelist

Regards

I send one spam test from a foreign mail account and it works well but 
then all messages that i send from there are marked as spam and even 
they are rejected without being scanned i allready put the address in 
the withelist file as: whitelist_from    [email protected] etc and the 
mail is still rejeced, the only way to remove from there is erasing the 
.spamassasin db and remove the files from SAteergrube, wich is the rigth 
way to prevent a address to be rejected,

the configuration in my exim conf even contains the followin lines

localpartlist noenvfromcheck = /etc/exim/whitelist
localpartlist noenvfromcallback = /etc/exim/whitelist
localpartlist nosarej = /etc/exim/whitelist
localpartlist nohdrsyncheck = /etc/exim/whitelist
localpartlist nohdrfromcallback = /etc/exim/whitelist

and the withelist file has the entries as mencioned above
any hints to erase an entry from the db

the configuration I used is from openna

thank you in advance
