Hi,
I am running qmail-1.03 MTA. Whenever a message is delivered to a
Microsoft Exchange Internet Mail Server version 5.5.2448.0, it says "421
Internal error.".
But when I telnet to port 25 and deliver the same message, the message
is received. Has it got to do something with the way MS exchange
RedHat 6.1 with qmail-1.03 and ucspi - 0.84.
qmail-smtpd is run by tcpserver and the -c value is 2000. But as soon as
it reaches 1247 sessions, it is not able to fork further processes, the
error message is:
tcpserver: warning: dropping connection, unable to fork: temporary
failure
This value
Is there any limit on tcpserver forking processes? I have configured
tcpserver to fork qmail-smtpd with concurrent sessions of 2000. I have
made a simulator that makes upto 2000 connections to qmail-smtpd. But
when the simulator reaches 1247 connections, tcpserver reports error
which is:
What is Bluetail Mail Robustifier? I couldn't find any pointers on the Net.
Thanks.

Actually, Algonet is part of Telenordia, and has in all about 300,000
users or so. All mail is run on qmail, though we're now using the
Bluetail Mail Robustifier as frontend for the qmail boxen.
