Hi,
I'm building a new qmail/qpsmntpd installation on an x86_64 platform.
All seemed to be going well until I tried connecting to qpsmtpd on port
2525.
It takes slightly longer than 30 secs to respond with the smtp greeting.
Here's my run file:
#!/bin/sh
QMAILDUID=`id -u qpsmtpd`
NOFILESGID=`id -g qpsmtpd`
PORT=2525
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
MAXCLIENTS=15
QPSMTPD_DIR=/var/qpsmtpd/0.3x
cd $QPSMTPD_DIR
HOST=`head -1 config/IP`
#exec /usr/local/bin/softlimit -m 50000000 \
exec /usr/local/bin/tcpserver -v -R -p \
-x /etc/tcp.smtp.cdb \
-c $MAXSMTPD \
-u $QMAILDUID \
-g $NOFILESGID \
$HOST $PORT \
./qpsmtpd 2>&1
# /usr/bin/speedy -Tw -- -M$MAXCLIENTS ./qpsmtpd 2>&1
As you can see, I've removed softlimit for now and disabled speedycgi
until I get to the bottom of the issue.
I'm launching the run file with strace from the command line. Here's the
last few lines of the output when I start it up:

accept(3,
When I telnet to port 2525, here's the output:
{sa_family=AF_INET, sin_port=htons(42921),
sin_addr=inet_addr("127.0.0.1")}, [16]) = 0

close(0) = 0
rt_sigprocmask(SIG_UNBLOCK, [CHLD], NULL, 8) = 0
accept(3,
Then, about 30 secs later:
tcpserver: ok 10541 localhost:127.0.0.1:2525 :127.0.0.1::42921

10541 loading plugins from ./plugins
10541 Connection from [127.0.0.1] [127.0.0.1]
Has anyone got any idea why there's such a delay between the initial
connection and the greeting response?
R.
