I hate to post unecessarily. But this is to thank everyone especially
Charles Cazabon and Dave Sill. The Big To Do patch worked and my
mails are zipping through (I run a very high volume mail server). I have

to
qmail.
This is the second instance where my life got saved because of this great
list.
Regards Manny
