What about the remedies suggested in the Postfix MILTER_README?
If the Postfix milter_protocol setting specifies a too high
version, the libmilter library simply hangs up without logging
a warning, and you see a Postfix warning message like one of
the following:
warning: milter inet:host:port: can't read packet header: Unknown error : 0
warning: milter inet:host:port: can't read packet header: Success
warning: milter inet:host:port: can't read SMFIC_DATA reply packet header:
No such file or directory
That's Sendmail libmilter hanging up.
