[Exim] callout give a defer instead a acept?

[ Picked text/plain from multipart/alternative ]
Hi, I set uo the callout a few weeks ago with great results! the spam
was reduced about 50%.

Any ways, I had a valid address that cannot send me an e-mail, because
the Exim give a:

"sender verify defer for <user@domain>: Could not complete sender
verify callout"

When I do a manual send:

HELO <domain>
MAIL FROM:<>
RCPT TO: <user@domain>
QUIT

I get a "250 ok" responce code, but in the DEBUG mode, I get:

6702 dbfn_read: key=christian@???
6702 callout cache: no address record found
6702 interface=NULL port=25
6702 Connecting to domain [216.241.15.x]:25 ... connected
6702 SMTP>> QUIT
6702 ----------- end verify ------------
6702 deny: condition test deferred
6702 LOG: MAIN REJECT
6702 H=localhost.localdomain (domain2) [127.0.0.1] sender verify
defer for <user@domain>: Could not complete sender verify callout
6702 SMTP>> 451 Could not complete sender verify callout

My ACL for the callout is as follow:

   deny    sender_domains = +callbackdomains
           local_parts    = !+noenvfromcallback
           !verify        = sender/callout=30s,random

Where "callbackdomains" is "*" and "noenvfromcallback" is "postmaster".

What I'm doing wrong? or why EXIM give me that DEFER instead the ACEPT ?

Thanks for any help.
