Problem with MailScanner, postfix and corrupt mails

Got one friday... They're extremely rare it seems.

I noticed something a bit curious about it in the logs:
<normal hold headers not included>
Mar 11 19:25:04 mail postfix/cleanup[9377]: B551923DCC:
message-id=<522842524315.TIN93887@

Mar 11 19:25:29 mail postfix/qmgr[16986]: A1CE723DDB:
from=<exqnclufhgenp at freemessage.com>, size=18870, nrcpt=1 (queue active)

Mar 11 19:25:29 mail MailScanner[5361]: Logging message B551923DCC.D5385
to SQL

Note the message ID. Perhaps doesn't matter(?).

Since it is a spam message, I've got both the mangled A1CE723DDB and the
nonmangled (but decoded, since I run MW) B551923DCC.D5385 ... and the
SQL/MailWatch logentry for it. If you want it Jules, you can have it
(off
list).
