[exim] 4.42 returns error where 4.31 does not.

Identical configuration files.

4.42
exim -v sbotsford
test42
.

Frozen (delivery error message)

(The stream stuff is to capture a copy of ALL incoming mail
in case I screw up big time with the spam stuff.)

Now using exim 4.31

exim -v sbotsford
test3
.
LOG: MAIN
<= root@??? U=root P=local S=276
postie# LOG: MAIN
=> sbotsford <sbotsford@???> R=spamcheck_router
T=spamcheck
LOG: MAIN
=> sbotsford <sbotsford@???> R=copy_stream
T=stream_delivery
LOG: MAIN
Completed


Ideas? Why is new exim returning error code 2
