Asunto: [exim-dev] [Bug 2604] exim does not send DATA to target host when verify callout hold and delivery cutthrough

With recipient verification removed and only the cutthrough accept line
present:

>From sender to inbound relay:


<< 220 smtpin001.a.snlmail.net ESMTP
>> ehlo asd

<< 250-smtpin001.a.snlmail.net Hello sarlonintman001.sargasso.net.uk
[2a05:e200:0:1::1]
<< 250-SIZE 52428800
<< 250-8BITMIME
<< 250-PIPELINING
<< 250-CHUNKING
<< 250-STARTTLS
<< 250 HELP
>> mail from:<me@???>

<< 250 OK
>> rcpt to:<invalid@???>

<< 550 Administrative prohibition
>> quit

<< 221 smtpin001.a.snlmail.net closing connection

>From inbound relay to mailstore host:


<< 220 mailstore001.a.snlmail.net ESMTP
>> EHLO smtpin001.a.snlmail.net

<< 250-mailstore001.a.snlmail.net Hello smtpin001.a.snlmail.net
[2a05:e200:1:74::2:1]
<< 250-SIZE 52428800
<< 250-8BITMIME
<< 250-PIPELINING
<< 250-CHUNKING
<< 250 HELP
>> MAIL FROM:<me@???>
>> RCPT TO:<invalid@???>

<< 250 OK
<< 550 Address invalid@??? unknown.
>> QUIT

<< 221 mailstore001.a.snlmail.net closing connection

So the sender just gets "550 Administrative prohibition"; even if
smtp_return_error_details is turned on at the inbound relay, it is hiding the
error.

Whereas when recipient verification is used, they get 550-Callout verification
failed:" "550 550 Address invalid@??? unknown.".
