It sure looks like you have a problem transport table or content filter
setting. Connections from the queue manager are mostly to the
unix-domain sockets of named transports, "private/smtp",
"private/local", ...
So, somehow this particular message resolves to a
"<base64-encoded-1473-bytes-of-line-noise>" transport.
So the question to you is:
* What sort of transport table(s) do you have in place
* What sort of content filters do you have in place
* Where is the problem queue file.
Your "postconf -nf" and "postconf -Mf" settings are also needed,
as well as any logging related to the queue file from "smtpd",
"cleanup" and "qmgr" (presumably it repeatedly logged adding
the message to the active queue).
