The error message means that dccifd tried to read more of the request
from the MTA (SpamAssassin in this case) but encountered end-of-file.
This happens while dccifd is looking for the lines containing recipient
user names, options, SMTP client IP addresss and host name, HELO value,
and SMTP envelope Mail_From value before the mail message body including
headers.  The ASCII protocol used between dccifd and SpamAssassin is
described in the dccifd man page or
http://www.dcc-servers.net/dcc/dccifd.html#Protocol


Are there any other indications of problems such as complaints from
SpamAssassin or other error messages in the log files such as
"write(MTA socket,3): Broken pipe"?

Has the SpamAssassin timeout for DCC checks been reduced?

When you say that `cdcc info` seems to be good, does that mean that
the delays to the DCC servers are at most a few hundred milliseconds?
