Setting up Qmail to Listen on Alternative Port 587
When setting my home connection to use port 25 to send my mail, I discovered that ATT does block port 25. This was making it hard to send my emails when on my home network. To fix this problme I have enabled port 587 to connect and send emails with.
Setup Qmail to use Port 587
You can probably do this in many different ways, but I used the following
cd /var/qmail/supervise/ cp -rf qmail-smptd/ qmail-smptd587/
Now we have to change this to listen to port 587
vim qmail-smptd587/run
Now find the following line
exec /usr/local/bin/softlimit -m 50000000 \ /usr/local/bin/tcpserver -v -R -l "$LOCAL" -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \ -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
and replace the smtp with 587
exec /usr/local/bin/softlimit -m 50000000 \ /usr/local/bin/tcpserver -v -R -l "$LOCAL" -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \ -u "$QMAILDUID" -g "$NOFILESGID" 0 587 \
Now save that file and edit the log file, unless you want it to log to the same file as smtpd
vim qmail-smptd587/log/run
Now find the following line
exec setuidgid qmaill multilog t s100000 n20 /var/log/qmail/qmail-smtpd 2>&1
and replace the log location to
exec setuidgid qmaill multilog t s100000 n20 /var/log/qmail/qmail-smtpd587 2>&1
Set smptd587 to run in /service/
Now we just have to make it start up with the rest of the qmail scripts
cd /service/ ln -s /var/qmail/supervise/qmail-smtpd587
Now your all set, if you check the listening ports it should be listed
netstat -nplt
One last thing, if you have a firewall on your server, you will want to open port 587
