How do I run qmail on port 587?

One of my users can not send out smtp port 25.

How do I set up my qmail server so that it is also listening on another port such as 587?

Hi Yukon,

This is not too hard to do. You'll need to make a quick update to your qmail install and possibly allow the additional port on your server or hardware based firewall. If you are running a server that resembles a Life with qmail install here are the steps to duplicate your port 25 config over to port 587.

  • Duplicate your $supervise/qmail-smtpd into $supervise/qmail-smtp587
Pick a name that makes sense. In my case I call it qmail-smtpd-auth. Substitute your name for my name in the following steps.
  • Update the run file so tcpserver is listening on port 587 in $supervise/qmail-smtp587/run
/usr/local/bin/tcpserver -v -H -R -l "$LOCAL" -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 587 /export/qmail/bin/qmail-smtpd

  • Make a link from /service to the new folder. Mine looks like this:
lrwxrwxrwx 1 root root 13 Sep 15 2008 dnscache -> /etc/dnscache
lrwxrwxrwx 1 root root 31 Sep 15 2008 qmail-send -> /var/qmail/supervise/qmail-send
lrwxrwxrwx 1 root root 32 Sep 15 2008 qmail-smtpd -> /var/qmail/supervise/qmail-smtpd
lrwxrwxrwx 1 root root 37 Oct 20 2008 qmail-smtpd-auth -> /var/qmail/supervise/qmail-smtpd-auth
  • Last you will need to update your qmailctl script.

I did mine pretty much the same way, however the one thing that wasn't mentioned is you *should* go and add your new / second smtpd service into your qmailctl file so you can control it with the rest of the your QMail daemons.... I never really found this step mentioned anywhere online, but I inferred it's need from the LWQ site.

in my case I simply grabbed the qmail-smtpd lines, copied and edited them:

[akneppar@mail1 ~]$ sudo cat /var/qmail/bin/qmailctl
Password:
#!/bin/sh

# description: the qmail MTA

PATH=/var/qmail/bin:/bin:/usr/bin:/usr/local/bin:/usr/local/sbin
export PATH

You will note, I was not nearly as creative as you in my naming, I simply called mine "qmail-smtpd2"

another nice tidbit we should mention is to verify you are listening on your new port:
[akneppar@mail1 ~]$ sudo netstat -natp|grep tcpserver
tcp 0 0 0.0.0.0:587 0.0.0.0:* LISTEN 28833/tcpserver
tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 28840/tcpserver
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 28830/tcpserver
