First guess:  NT users?  What do I win?

Heh.  Tomorrow I meet with a possible customer that wants to switch
from NT to Unix.  He is worried about sending emails, since the
current NT box barfs and locks up whenever 1300 emails are sent at one
time to an opt-in list.

I told him about the time I used an SM51 SS10 running OpenBSD 2.7 +
postfix and sent 20K emails all at once.  Not even a burp :-)

Actually the Windows-based email merge sw they were using could only
send in batches of 500 or so before crashing.  Oops.  Poor NT admin
had to sit at a desk in the NOC for 8 hours clicking away, sending
23,000 emails in batches of 500.

Meanwhile I was logged in via SSH from home and ran a perl script that
generated a lovely stats report from the maillog.  Took about 30
minutes to set up the way I wanted, then 5 minutes to run.  

Unix is good.
