Cannot send mail with Qmail

Hello, I have been trying this one problem with qmail for ,some time
now; basically I installed qmail/vpopmail on my solaris 9 system.
Followed the tutorial on qmailrocks.org for the installation; the
compilations was successful (no errors).

The problem is I can receive mail from remote systems but I am unable
to send mail to remote systems, I can however; send mail between local
accounts on my mail server. Now; I have analyzed the problem from many
aspects.

Here are the services I compiled:
netqmail-1.05
ucspi-tcp-0.88
vpopmail-5.4.13

My /var/qmail/supervise/qmail-smtpd/run looks like this (note: my mail
server is mail.mydomain.com for the sake of this example)

#!/bin/sh
QMAILDUID=`/usr/xpg4/bin/id -u vpopmail`
NOFILESGID=`/usr/xpg4/bin/id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
LOCAL=`head -1 /var/qmail/control/me`
exec /usr/local/bin/softlimit -m 30000000 \
/usr/local/bin/tcpserver -v -r -l "$LOCAL" -x /etc/tcp.smtp.cdb -c
"$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
/var/qmail/bin/qmail-smtpd mail.mydomain.com \
/export/home/vpopmail/bin/vchkpw /usr/bin/true 2>&1


My /var/qmail/supervise/qmail-pop3d/run is as follows

#!/bin/sh
PATH=/var/qmail/bin:/usr/local/bin:/usr/bin:/bin:/sbin:/usr/ccs/bin:/opt/csw/bin
:/bin
export PATH
exec /usr/local/bin/softlimit -m 3000000 \
/usr/local/bin/tcpserver -H -R -v -c100 0 110 qmail-popup
mail.mydomain.com \
/export/home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir
2>&1


My /var/qmail/supervise/qmail-send/run is as follows

#!/bin/sh
exec /var/qmail/rc


So now qmail is running on my system and can be verified using
#qmailctl.solaris stat

/service/qmail-send: up (pid 3486) 8 seconds
/service/qmail-send/log: up (pid 3485) 8 seconds
/service/qmail-smtpd: up (pid 3495) 8 seconds
/service/qmail-smtpd/log: up (pid 3494) 8 seconds
/service/qmail-pop3d: up (pid 3501) 8 seconds
/service/qmail-pop3d/log: up (pid 3502) 8 seconds
messages in queue: 0
messages in queue but not yet preprocessed: 0

And to make sure I scanned the ports from 1-200 and ports 25 and 110
were open, and in addition to that I ran a ps -ef | grep error to
see if there were any errors with any of the mail services.

root 374 370 0 Jul 14 ? 2:20 readproctitle service
errors: .................................................

As you can see from the sequence of uninterrupted dots, no errors were
detected.


So let me show you what the logs say when I execute a command using
qmail-inject to send a mail from local system to a user on yahoo mail
server. me@mydomain.com -> test@yahoo.com

# echo to: test@yahoo.com | /var/qmail/bin/qmail-inject

# tail -f /var/log/qmail/qmail-send/current

And here is the output from the network layer using tcpdump (Note:

yahoo mail server)

>From the logs and tcpdump it appears that the delivery of the message
436 was a success, and that it was actually delivered to the remote
host as we can see from the tcpdump output, however after checking the
remote mail box I did not see the message i sent.

I can receive mail from the same remote system I tried sending to with
no problems. So it cannot be a DNS problem since the remote mail server
didn't have a problem resolving my mail server address.

I even tried the other method of sending mail by telneting to port 25
and constructing the message, in either case; everything seems to be a
success, no hints or indications of an error. My last guess would be
that it is a problem with one or more of the control files.

At this stage I tried every thing and frankly ran out of ideas. If you
see an error that I don't or have any queries or suggestions please
don't hesitate to reply.

Thank you.

The entry:
@4000000044bc12610e6fbf54 delivery 2: success:
67.28.113.70_accepted_message./Remote_host_said:_250_ok_dirdel/

indicates the the email from you to a yahoo address was delievered to
the mail server having Ip address 67.28.113.70.

not sure what you are looking for. If the message did not make it to
the recipient they need to talk to Yahoo. Your server could have been
black balled or the message deemed as spam and so handled.

Try sending to a different external email address.
