Hello, I have been trying to solve this problem 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.

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

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 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.
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.
