No. I'm trying to drop undefined addresses :)

"drop" is not very good idea, since it bounces message back. "discard"
is good. Also I found that my relay is using qmail and it adds field
Delivered-To: which contains envelope To from original message, so
everything is much simpler now.
This is what I have now for "after DATA" ACL:
check_message:
require verify = header_syntax
require verify = header_sender
discard condition = ${if def:header_delivered-to: \
{${lookup{$header_delivered-to:}
wildlsearch {/etc/exim4/allowed_rec} {no}{yes}}}\
{no}\
}
logwrite = Delivered-To: user $header_delivered-to: is not allowed.
accept
Works perfectly, exactly as I wanted. Only problem was with logging -
I wanted to use log_message, but for some reason it didn't write this
message to my log. logwrite works though.
So, thanks for idea :)
