[exim] Multiline "OK" responces of remote servers

Hello.

I have found in logs, that when Exim sends mail and gets multiline "OK"
responce after DATA has been sent, is saves truncated "OK" message in
the log, thus it is impossible to see accepted message ID. Here is an example:

Sep 7 15:12:01 chess exim-smtptls[93181]: 1ITbkS-000O3j-Hv => aokomelchenko@??? R=dnslookup_self T=remote_smtp H=mx.mtrade.ru [195.239.203.122] C="250-Transmission in progress. Stay tuned\\n250 Ok, message saved <Message-ID: >"
===

Message id is truncated.

I am using Exim v4.67
Who is wrong here? Is there any configuration workaround possible for this
case?

Thanks in advance.
