Assunto: [exim] acl: different behaviour for messages in verify = ...
Hello,

using 4.63:

in my RCPT ACL I've:
    ...
    require message = Huh (sender)!
        verify  = sender/callout=random


    require message = Huh (recipient)!
        verify  = recipient/callout=random
    ...


I expected exactly my message in the server response, nothing but my
message. But in the following examples you'll see that it's true only
for the recipient verification.

Now testing it with BAD SENDER:

    # exiacl -f pitti@??? -t info@???
    **> /usr/sbin/exim -C /etc/exim4/exim4.conf -oMi 145.253.107.250 -bhc 172.20.1.8

     Sender verify failed
    < 550-Verification failed for <pitti@???>
    < 550-Previous (cached) callout verification failure
    < 550 Huh (sender)!


Now testing it with good sender but BAD recipient:

    # exiacl -f hs@??? -t drehrumbum@???
    **> /usr/sbin/exim -C /etc/exim4/exim4.conf -oMi 145.253.107.250 -bhc 172.20.1.8

    > EHLO schlittermann.de
    < 250-paff.bioz.tzdresden.de Hello schlittermann.de [172.20.1.8]
    < 250-SIZE 52428800
    < 250-PIPELINING
    < 250-STARTTLS
    < 250 HELP
    > MAIL FROM: hs@???
    < 250 OK
    > RCPT TO: drehrumbum@???
    LOG: H=(schlittermann.de) [172.20.1.8] F=<hs@???> rejected RCPT drehrumbum@???: \
     response to "RCPT TO:<drehrumbum@???>" from mail.namos.de [145.253.108.53] was: \
     550 <drehrumbum@???>: Recipient address rejected: User unknown in local recipient table
    < 550 Huh (recpient)!



Is it a but or just my misunderstanding?

From a short look into acl.c, around line 1941, I get the feeling, that
it's really handled in a different way.
