Still see some dropped header information - drastically less, but not 0.
So I'd say there still might be a race condition or error handling that
isn't right.
I tried to move the outputbuffer handling into ::output, moving any
existing outputbuffer contents to a temporary buffer, killing the
outputbuffer, and dumping that temp buffer first once connected was set,
but I was still getting unparseable relays. Then I pulled the connection
attempt for each line completely letting everything be buffered and just
did the connection attempt after the _eoh was buffered to the
outputbuffer (turning on connected before the Connect call as it was
before - just done after everything was buffered). This also gave
unparseable relays, but in both of these cases at least all received
headers were examined by spamd.
So I'm thinking that the dropped lines are one problem - and either of
the above solutions might help with that - I don't know - but that there
is also a received header formation problem that spamd doesn't like the
result of.
A sample header in the text e-mail might be
Received: from mail02.connect.hpe.com (mail02.connect.hpe.com
[204.92.22.193])

and I see
