This could be due to spamassassin taking long enough to process the
message that sendmail timed out the milter connection.  Note that the
incorrect samples have no spamassassin headers at all.  If you take a
look at the maillog, check for a "sm-mta[xxx]: Milter: (xxx) timeout"
error followed a few seconds later by a "spamd[xxx]: clean message in
xxx seconds".  Raising the milter timeout values in your sendmail
config file or turning off DNS checks in spamassassin will help here.
