Mm.. it's true.. :) I've tried this perl script:
open MAIL, "|mail dani";
print MAIL "Hi!";
If I run it under the Ultra-1 and sendmail, it never ends.. because it
keeps delivering them one by one and doing all the job.
From the Pentium Pro running ZMailer, I can set counter to 5000, and
have all them delivered in 2 or 3 minutes.
So for each message, the delay is higher in zmailer, but the speed (in
messages per second) under ZMailer is *much* faster.
I've done it all locally -no network- and just one smtp conection at
time. I guess that if I had many simultaneous conections, the results
would be even more impressive :)
Thanks for the info, It has been very helpful.
Keep on the good job,
