Dear Sir:
* I'm here not for another blamming-war, just some experience.
Yes, I'm a very big 'newsletter' system administrator. Now I have to
send 400K+ newsletter in less than 8 hours (not a day, since some news
are time-intensive) per day.
In fact, I'm a new comer for qmail, and our system is now on one
single
ultra2 workstation w/ 256MB RAM and 2*2GB U-SCSI disks. This is a very
old model, about 2 years ago, so the computing power is surely weak
than
today's PII/PIII, even some P-200+ I think.
Can I achieve my target? Yes, I can send 400K+ letters in less than 8
hours.
But unfortunately, it works on sendmail 8.9.x, not qmail.
The mail reason that I can't switch to qmail is that I'm NOT familiar
with
qmail in early days, so I chose sendmail.
But now I 'almost' give up sendmail, because I can't add/change
functions
on it via a simple way - I mean something like qmail. I have the
bat-book
about sendmail, but I only use it to tune the 'options'.
I've read all the articles about the topic 'qmail speed'. Now I'm
wonder
that if qmail can do this too? If the design spirit of qmail can't
afford
such high-loading task in short time, then sendmail takes the chance
back.
I'll try to move my system to qmail recently, and give it a try, I
think
now I have more control on qmail than before, does 40K+ letters in 8-
hour
possible? I might have some comments soon. My new machine is a
PII-350, w/
256MB RAM and 2*4G UW-SCSI disks, the OS is FreeBSD 3.1.
As I know, hotmail use qmail as its base(?) but hotmail is slow, slow,
and
unreliable 'sometimes'. I don't know what will happen if hotmail
choose
sendmail as its base now, but I'm curious on this topic.
Sorry for this posting if not suitable here, and thanks for any kind
of
comments about this.
Regards.
