My setup: sendmail, Solaris 9, SA 3.1, dcc and razor.  While things are
pretty slow right now (no students), a couple of big mailing lists got
launched yesterday, after upgrade to 4.49.  I definitely noticed how
much faster MailScanner churned thru the multi-hundred message lists.
We use VERP, so there is one message per subscriber on a list.  Martin
Hepworth's "1/3 faster" estimate agrees with my subjective eyeball
measure from watching xload for my mail server.  Great work, Julian!!
