how to configure postfix to send email out for a hosted domain

Hiya all,

i'm having a problem with my Suse server.
I've installed on it ISPConfig with several websites.

Also i've an OScommerce installation running on it...
Let me describe my scenario:

a user is buying something on the shop.
When the purchase is done, oscommerce send a confirmation email to the user.
Everything is fine but not if the user's email domain is hosted on the server.

ie:
[email protected] purchase something -> email sent correctly.
[email protected] purchase something -> the postmaster (myself) receive a bouceback like this:

Code:

 The e-mail system was unable to deliver the message, but did not report a specific reason.  Check the address and try again.  If it still fails, contact your system administrator.
            < server1.xxxxxxx.com #5.0.0 X-Postfix; unknown user: "demouser">

I think the mailserver is not sending the email because the email domain address is hosted on the server.
The point is that the domain has not the mailserver on my server but the client is managing it. The MX server is outside the ISPConfig server...

I hope everything is clear...
How can I configure postfix to look outside the server and send the email??

thanks

Any idea??

 

Does [email protected] exist in /etc/postfix/virtusertable? What's the output of

Code:

postconf -n

?

 

Hi falko,
inside the vitusertable there isn't that user.

This is the output postconf -n:

/etc/postfix/virtusertable isn't included in your Postfix configuration. Please run

Code:

postconf -e 'virtual_maps = hash:/etc/postfix/virtusertable'
/etc/init.d/postfix restart

And then you must create the email address [email protected] in ISPConfig, because if it doesn't exist, you can't send to it.

 

Sorry, but I'm not getting that.

Why OSCommerce can send email to "[email protected]" and cannot to "@hosteddomain.xxx" ?
Just to be clear the client has just pointed one A Record on my server.
They have their own server for the website and for the email as well.

They are pointing to my server for shop.clientdomain.xxx

Thanks!

 

You must create a "CatchAll Account" if you want to send emails to @hosteddomain.xxx.

 

I'm worried to do some changes to the actual configuration of the entire server because I've got a lot of website on it and they are working all fine.

So I'd like to be really sure before do anything.

I just need ISPConfig to be able to send the email to a @hosteddomain.xxx email address but without looking inside "himself".
Because, of course the user do not exists on the localhost. The email address is hosted somewhere else, where the real mailserver is.

Is there a way to do it?
Because now you gave me 2 information and I'm not sure witch way I should take.


For example if I create the user in ISPConfig and enable the "External Mailserver" option will it send the email without looking inside the server for the user?

Thanks!!

 

Well, at least you must do this:

Code:

postconf -e 'virtual_maps = hash:/etc/postfix/virtusertable'
/etc/init.d/postfix restart

Yes.

 

Hello again.
I did what you said Falko.
Now it seems to work with the main email "[email protected]", this is the email address that i've add to ISPConfig,
but it is not working if a user with the same domain but a different address i.e. "[email protected]" purchases something!

Do I have to create every user that my client has in is mailserver??

Are we sure isn't there a solution to "route" postifix directly outside itself (localhost) to look for the user and just send the email??

Many thanks!

 

This is the log from postfix:

Code:

Jun 21 15:14:25 server1 postfix/qmgr[22433]: EBFAA254058: removed

As you can see the email to [email protected] has been delivered with no problem (because now it is in ISPConfig and the "External Mailserver" has been enabled), but the other email to [email protected] has not (because the user doesn't exist in ISPConfig)

I really need a solution for this, if anyone has an idea please tell me!

 

Can you post the contents of /etc/postfix/local-host-names and /etc/postfix/virtusertable? What's the output of

Code:

postconf -n

?

There must be an email account for [email protected] on the receiving mail server.

 

I'm sorry but for privacy reasons I can't post here the content of /etc/postfix/local-host-names and /etc/postfix/virtusertable
Maybe if you tell me what I have to look for...

This is the output for

postconf -n:

Of course there is an account for [email protected] on the receiving mail server but, as I can understand, postfix just looks inside without trying to send the email. It thinks to be the mailserver. It looks for the user and cannot find it. So I, as a postmaster, receive the email of not delivery report with "user unknow" as error.

Making a practical example:

this is the shop address: shop.examplegift.com
shop owner email address: bookings.examplegift.com
client1 email address (generic): [email protected]
clent2 email address (same company): [email protected]


Case 1:
Someone with a generic email address (client1) registers himself on the OSCommerce shop.
When he purchases something there are two emails sent. One email is sent to the shop owner and the other to the client.
Mail to the owner: OK (since I've added the user on ISPConfig - see previous post)
Mail to client1: OK

Case 2:
Someone from the same shop's company, or someone else for whom i'm hosting the website on the same server, purchases anything this is what happens:

Mail to owner: OK
Mail to client2: postmaster receives the NDR (user unknow)


I hope that the picture of the situation is clearer now.
This is really odd and for me, not a good linux user , it is very difficult to fix something like that.

Thanks

 

Code:

virtual_maps = hash:/etc/postfix/virtusertable

is still missing in /etc/postfix/main.cf. Please add it and restart Postfix (I mean it).

 

nox171 did your customer setup in oscommerce admin to send from the user "email address" hosted on your server or from one of their existing users "email address"

 

I have created the email address in ISPCofig and then enabled the "external Mailserver" funcion, but the user is not hosted on my mailserver.

Falko I tried the command again as you suggest:

Code:

server1:~ # postconf -e 'virtual_maps = hash:/etc/postfix/virtusertable'
server1:~ # /etc/init.d/postfix restart
Shutting down mail service (Postfix)                                 done
Starting mail service (Postfix)                                      done
server1:~ #

but then looking in it I still don't see the /etc/postfix/virtusertable!

Do you know why??

 

Can you add

Code:

virtual_maps = hash:/etc/postfix/virtusertable

manually to /etc/postfix/main.cf then and restart Postfix?

 

I opened the file but the virtusertable line was already there!


Someone can tell me what's going on here??

 

Can you run

Code:

updatedb
locate main.cf

and post the output?
How did you install Postfix? Did you use your distribution's package, or did you compile it yourself?

 

here the output

Code:

/etc/postfix/main.cf
/etc/postfix/main.cf.default
/etc/postfix/main.cf.orig
/etc/postfix/main.cf.SuSEconfig
/var/adm/backup/postfix/main.cf
/var/adm/SuSEconfig/md5/etc/postfix/main.cf

I didn't install the box, it has been done by the previous IT manager.
It should be a normal installation of ISPConfig following the how to in this forum.
The distro is a suse.
