Mention all your domains in /var/qmail/control/rcpthosts to which user can send mail.

Add domains names to /var/qmail/control/locals and /var/qmail/control/virtualdomains then restart qmail and check.

thanks for reply
but still mail are going outside

Hi,

You can put a non-existent host in the smtproutes file, so when qmail tries to deliver a message that is not local it fails with a "permanent error"
You may also use queuelifetime to specify the time (e.g. 600) that the message stays in queue before it bounces back (default is 1 week)

Regards

i add abc in smtproute file and restart qmail but still mail go outside

What abc and what smtproute file?
You need sometrhing like:

Code:

:x.x.x.x

where x.x.x.x is the IP of a non existent host, or at least a host that does not run a mail server.
The filename is smtproutes and it's located in /var/qmail/control/smtproutes

Thanks very much

solved , but it does not give any error when i send to external id it just send but not receive on external id and any thing to do to get returned back error

Amar

You don't pay much attention to replies.
I've already told you, that you need to specify a small amount time in /var/qmail/control/queuelifetime, so yo don't have to wait a week to get the bounce back message.

Hi

i entered 200 in /var/qmail/control/queuelifetime, and when i send message to outside mail i get delivery fail message after 1 week pls help

Regards
Amar

Hi,

I don't know what you did, but I've just tested with a queuelifetime of 60sec and it worked, as you can see:

AFAIK qmail tries for the first time to send the message and then retries (every 5mins?) until the queuelifetime expires. Then tries for a last time and bounces back the mail.
Even though there is no need to restart qmail, try to restart it and test to see what happens

Regards

i kept 200 in /var/qmail/control/queuelifetime, and restart but still not get bounce back i will baunce back after 1 week which is default values i think qmail not take value from queuelifetime need to edit any other files??

Regards

No, it's queuelifetime that specifies the time a mail stays in queue
What gives:

Code:

/var/qmail/bin/qmail-showctl |grep queuelifetime

Maybe you're doing something wrong. You may try:

Code:

echo 200 > /var/qmail/control/queuelifetime

Hi
/var/qmail/bin/qmail-showctl |grep queuelifetime

shows output as
queuelifetime: Message lifetime in the queue is 200 seconds.

queuelifetime~: I have no idea what this file does.

and

echo 200 > /var/qmail/control/queuelifetime

shows nothing output
