Some of our preliminary results are causing us to scratch our heads.  
Here's some output from the mailman smtp log:

Jul 17 07:49:20 2005 (4460) <20050717122437.79C6BD0C57 at rekin6.o2.pl> 
smtp to lam for 443 recips, completed in 621.976 seconds
Jul 17 07:52:21 2005 (4460) 
<mailman.142.1121603081.4458.lam at lam-mpi.org> smtp to lam for 141 
recips, completed in 180.912 seconds
Jul 17 07:52:33 2005 (4460) 
<mailman.143.1121603081.4458.lam at lam-mpi.org> smtp to lam for 8 recips, 
completed in 12.025 seconds

This is from a mailing list named "lam".  The total number of 
recipients from the three lines adds up to the number of subscribers on 
the list who have mail enabled, so that's not puzzling (443 + 141 + 8 = 
592).

But we're wondering why one post on the LAM list results in 3 
consecutive lines in the mailman output log -- it seems like there 
should be a whole bunch of lines saying "smtp to lam for 
[SMTP_MAX_RCPTS] recips..." or just one line saying "smtp to lam for 
[total] recips..."

Why three?
