It's an exim thing. One way to do this is to use:
control = fakereject
in an accept clause. The connection site gets a 550 rejection but
the message is accepted for delivery. See Section 39.18 of the
manual. Note it says this facility should be used with extreme
caution.
You'd write something like:
accept
condition = ${if <{$message_size}{80k}{1}{0}}
spam = spamd:true
condition = ${if >{$spam_score_int}{80}{1}{0}}
control = fakereject/This message scored $spam_score points.
(I *haven't* tested the above.)
You might want to redirect the message to a special mailbox,
delivery address etc. I use this technique to pick up viruses that
are detected by just one of the virus scanners I use, and not both.
However the last thing you want to do is actually deliver the message
in this case. That's why I divert the message elsewhere.
