[exim] *sigh* luser issues..

Hello all,

we have SA implemented in Exim, tags at 6 and rejects when it's over 10.
We have a few thousand users that are all quite content.

Except for one.

How would I implement an accept for email addresses?

we currently have this in place to check for valid recipients:

deny message    = That is not a recipient that we take mail for.
  condition      = ${lookup {$local_part@$domain} 
cdb*@{/usr/local/etc/exim/cdb/recipients.cdb}{no}{yes}}
  log_message    = Bad recipient

And I would assume to have something like the postmaster : abuse check

accept local_parts = postmaster : abuse
  domains        =  +relay_to_domains

accept condition = ${lookup {$local_part@$domain}
cdb*@{/usr/local/etc/exim/cdb/spam_me.cdb}}


where the spam_me.cdb would contain user@???

Would that work?

Thanks in advance
