qmail to use port other than 25 for smtp?

[jme]

Hiya guys,

I have qmail running on my email server which I have just installed using the excellent tutorials at www.qmailrocks.org, and all is workinig great internally, but I cannot send or receive messages from the big-wide-world.

I have checked and my ISP blocks port 25, so I have paid for the mail reflector from no-ip.com to redirect all port 25 traffic to another port on my computer. However, when I am setting this up (on the no-ip.com site) it says that I don't have a emailserver on that port. I have tried searching and cannot see how I can change the default port for smtp traffic from 25 to 2525.

I have read that it maybe soomething to do with the /service/qmail-smptd/run file, but I cannot see any indication of where to change the port number within the file.

Any suggestions or ideas would be greatly accepted.

Many thanks,
Jamie

Change the port that tcpserver/inetd/xinetd listens on for qmail-smtpd. See
the documentation for the relevant software package for details.

Dear jme,
Hello,

I belive its qmail-smtp which use port 25 and if you want to run qmail-smtp on other port then you need to look following file.

/var/qmail/control/conf-common

# Host and port to listen on
# We listen on the IPv4 local ip by default
TCPSERVER_HOST=0.0.0.0
TCPSERVER_PORT=${SERVICE}

Change TCPSERVER_PORT=1025 for example and restart service

Best Regards.
