Mails do slip through MS..

Hi there,

somehow some mails do slip through, but in the logfiles it seems that MS
scannes them.

But then SpamAssassin reports these Mails as spam or some virusscanners on
the client-side report these mails to be infected.

After checking those mails, and look through the Mail-Log, all i found was
this:

Jan 18 01:15:32 mail sendmail-in[24308]: j0I0FUBP024308:
from=<fwv at toppowerproduct.info>, size=1491, class=0, nrcpts=1,
msgid=<D95D7316.C78051E at toppowerproduct.info>, proto=SMTP, daemon=MTA,
relay=28.255-0.172.63.66.in-addr.arpa [66.63.172.28] (may be forged)
Jan 18 01:15:33 mail MailScanner[22054]: New Batch: Scanning 1 messages,

Jan 18 01:15:41 mail MailScanner[24333]: Creating hardcoded struct_flock
subroutine for linux (Linux-type)


it seems that MS says in the log it is checking the mail, but the mail
does not contain the MS-Headers.
After checking against other not scanned mails, this only happens if the
mail was received as MS dies of "old age".

Greetings

Marcel
