Hi,
we are about to forward messages from outside to an internel
Exchange2013 server.
It seems that the Exchange2013 does not cooperate well with the callouts
for recipient verification:
mail from:<sender@???>250 2.1.0 Sender OK
rcpt to:<empfang@empfangsdomäne.local>
250 2.1.5 Recipient OK
data
354 Start mail input; end with <CRLF>.<CRLF>
Test
.
550 5.1.1 User unknown <------------- TOO LATE for Exim
--
The "User unknown" response is delayed until the end of the data phase.
Can anybody confirm this behaviour?
Was anybody successful in changing the behaviour to what Exim
expects (5xx already at RCPT time)?
Yes, I know, using cutthrough routing/delivery could partially solve my
problem. But it's limited to one recipient per message, if I got it
right.
Best regards from Dresden/Germany
Viele Grüße aus Dresden
