[Mimedefang] dsn=4.0.0, stat=I/O error: I/O error

We brought up the new architecture "sendmail -> trend micro -> sendmail +MD 
+SA " into production, the system load looks very good, but we have 2 issuses:

1. There are messages with dsn=4.0.0, stat=I/O error: I/O error got stuck 
in the queue.  The log shows:

    Jul  8 08:47:36 mail-a-eth0 sendmail[89]: [ID 801593 mail.info] 
h67GiCUr009106: to=<xxxxx at haas.berkeley.edu>, dela
y=23:03:20, xdelay=00:00:00, mailer=local, pri=2008035, 
relay=localhost.haas.berkeley.edu., dsn=4.0.0, stat=I/O error: I/O error


   Some of these were sent to majordomo mailing list on localhost, some are 
from other host's majordomo owner to subscribers on localhost. One of them 
was sent out from one local address to 7 other local addresses, all 6 
received it but one, and the error message is I/O error.  It was a text 
message with a few URLs, no attachment.

2. There are duplicate messages sent to aliases.  This problem was 
corrected after I removed the /etc/mail/aliases line in the second daemon's 
sendmail.cf file. I believed each daemon looks up the aliases file and 
interpreted it twice.  What I am not clear is why this didn't happen to 
mailing lists.

  Stephane, I CCed you (sorry), because you have define(`ALIAS_FILE', 
`/etc/mail/aliases') in both mc files.  Have you run into this problem?

  Please also note in the error message 
relay=localhost.haas.berkeley.edu.  I have "always_add_domain'" in both 
sendmail.cf file. Should I remove it from the second daemon's cf file?


The box is Solaris 8 with a virtual IP, sendmail-8.12.9, TrendMicron Virus 
Wall3.8, mimedefang2.33 patched, SA2.55.


Attached are my mc files and below is startup script:
  /etc/iscan/sendmail;
/usr/lib/sendmail -L sm-mta1 -bd -q45m;
/usr/lib/sendmail -L sm-msp-queue -Ac -q30m;
/usr/lib/sendmail -L sm-mta2 -bd -q45m -C/etc/mail/sendmail.cf.delivery;
/usr/lib/sendmail -Ac -qp2m -C/etc/mail/sendmail.cf.delivery;


Thanks in advance for any suggestions.
