Ok, here an incoming message from steelrat@??? with
protocol=esmtp, it will be sent to spamcheck transport as the protocol is
not spam-scanned. Fine.

Here's a new message from nobody@spamshield with protocol=local (called
from user nobody). This protocol is not spam-scanned, we must send it to
spamcheck... which is creating your mail loop.

spamcheck is done with the original message, it as been delivered.

Looping message comes back.

There is an error in the program you call from spamcheck. It should use
the spam-scanned protocol instead of the default local one and also should
set the envelope from to the original value instead of letting Exim use
the default username@hostname (nobody@spamshield). To achieve this, the
command that pipe the message back to Exim should contain '-oMr
spam-scanned' to specify spam-scanned as the protocol and '-f $sender'
where $sender contains the original envelope from of the message. Are you
using Andi Gohr's spamcheck.pl or your own script? btw, I had to change
that spamcheck.pl so that bounce would not be deleted. When the sender is
empty, it sets it to "<>" which I had to change to "\<\>".
Also note that both -f and -oMr commands are only available to trusted
users. is the user nobody in your trusted user list?
