The fact that the delivery 'Mar 15 13:40:04 firewall sendmail[401]: NAA00401:' does not generate a dlf record is a bug.

When the line

  Mar 15 19:39:40 mailhost sendmail[2178]: TAA02178: \
   from=<foo@hotmail.com>, size=0, class=0, pri=0, \
   nrcpts=0, proto=SMTP, relay=[1.84.7.150]
 
 

occurs in the input, and there is no line carrying the same queueid, the line is discarded, and reported as skipped: any to- or from- line, lacking any partner, will get discarded.

Lines like:

  Mar 15 13:40:19 firewall sendmail[456]: alias database \
   /etc/aliases.db out of date
 
 

wil get discarded

EXAMPLES

To process a log as produced by sendmail:

  $ sendmail2dlf < mail.log
 
 

sendmail2dlf will be rarely used on its own, but is more likely called by lr_log2report:

  $ lr_log2report sendmail < /var/log/maillog
 
 

BUGS

When queueids are being reused within one logfile, behaviour is unpredictable. Incomplete logsnippets (e.g. from-lines without to-lines) are not treated well.

It is reported events like this occur in sendmail log files:

  SAA14845: from=<>, size=146990, class=0, pri=176990, nrcpts=1, 
   msgid=<092246.09986@rly-yc03.mx.aol.com>, proto=ESMTP, 
   relay=omr-d06.mx.aol.com [205.188.156.71]
  SAA14845: to=joe@mailhost, ctladdr=<joe@example.edu>, delay=00:00:01, 
   mailer=local, stat=User unknown
  SAA14845: to=<joe@example.edu>, delay=00:00:01, mailer=local, 
   stat=User unknown
  SAA14845: SAA14846: postmaster notify: User unknown
  SAA14846: to="|exec /usr/local/bin/procmail", ctladdr=ann@mailhost (2217/10), 
   delay=00:00:00, xdelay=00:00:00, mailer=prog, stat=Sent
  SAA14846: to=bob@imap-ns, delay=00:00:01, xdelay=00:00:01, mailer=esmtp, 
   relay=apex.example.edu. [152.19.4.80], 
   stat=Sent (Message received: GVV8N400.CMX)
  SAA14846: to=eve@mailhost, delay=00:00:01, xdelay=00:00:00, mailer=local, 
   stat=Sent
 
 

Note that SAA14845 has _two_ final to= lines, while the from= line states nrcpts=1. This blows the axiom of this script away. We haven't decided yet on how to deal with this...

THANKS

Edward Eldred, for finding and reporting a bug.
