Multiple domain email SMTP mailboxes

[LeeT (Lee)]

NethServer Version: 7.6.1810
Module: Email

Hello,

First of all thankyou to the developers, maintainers and community for creating NethServer - I have found it fairly easy to use so far and hope I can pay back some day…

I am presently attempting to set up mailboxes for multiple domains (e.g. lee@domainA.com and lee@domainB.com). I have changed the DNS A record for both domains to point at my NethServer machine and have managed to set up the first email address. For the second, @domainB does not come up as an option when I go to Users and Groups->User name (it is fixed to @domainA.com). I have created a new domainB.com domain in Configuration->Email.

When I send an email to lee@domainB.com I get

lee.domainA.com gave this error:
lee@domainA.com;: Recipient address rejected: undeliverable address: User unknown in virtual alias table

I’ve read all the other threads I could find on this topic, as well as the docs, but can’t seem to find clarity on this. I have the following questions:

Is multiple domain SMTP email possible with Nethserver via the UI, or otherwise?

Is there a guide to add extra email domains and SMTP?

What is the virtual alias table and where do I edit it?

Can you see any fundamental misunderstanding I’m making?

Here are the related threads I found:

Nethserver as Multiple domains Email Server only, placed in DMZ

Salut Bogdan, I also tried SOPHOS but I don’t understand why for business is so “empty” and for home is so “plenty”. It’s more intuitive but like I said … I used ENDIAN about 2 months and I am very pleased. Now we try to sell ENDIAN in Romania. I have tried some email servers till now (AXIGEN on Windows - is in production but now with only 2 domains, ZENTYAL 4.0 - in production, the rest of domains migrated from AXIGEN, iRed, and others). I read about NethServer on ZENTYAL forum and I want t…

Multiple Email Domains Send/Receive Emails

Hello, Is it possible to use Nethserver to send/receive emails for multiple domains such as abc.com, xyz.com etc? This server is connected to an AD for domain abc.com. But i also would like to receive and send emails as xyz.com. So far what i did is created alias for user1@abc.com --> user1@xzy.com. I connected the account user1@abc.com on thunderbird but with email address as user1@xyz.com. But its not sending out email. Is it not possible or i need further config? Also if i point the MX re…

2nd Email Domain

If the accounts domain is removed from “Email > Domains” page it is configured to be accessible from trusted clients only. In other words mail to xyz@mydomain.com is allowed from members of mydomain.com only. See also:

I’m trying to do exactly what you have achieved, but I’m failing. I posted here Mail alias failure with my probelm. How do you have things set up so it works for you?

Multiple DNS domains with Wildcard support

NethServer Version: 7.3.1611 (rc3) Module: DNS Hi, I’m trying to configure NetHServer to handle multiple domain names with wildcard support on some. My objective is not to have a webserver with virutal hosts running on the nethserver, but to have a real DNS server that I can configure. I can’t find any configuration for domains in the web admin panel, and no other package to handle DNS configuration is available in Software center. Do you know if I can achieve what I want to do wit NethSer…

Is multiple domain SMTP email possible with Nethserver via the UI, or otherwise?

By design, no. NethServer do not support fully customizable multiple domain mailboxes.
You can have only one userbase and only one set of mailboxes/aliases, but these could be bonded to multiple domains.

Thank you @pike,

Let me rephrase:

Is it possible, by design, to send and receive email from lee@domainA.com and lee@domainB.com via a single NethServer Virtual Server instance?

Can this be done by “bonding to multiple domains”?

[pike (Michael Kicks)]

Only on the same mailbox.

[LeeT (Lee)]

i.e. the same domain, or can the same mailbox have muliple domains?

Yes, but if you want those addresses to belong to different user accounts it will be ugly (if they’re going to be the same account, it’s quite simple; just set up an email alias). You’d set up two accounts, call them lee1 and lee2. You’d then create a mail alias of lee@domainA.com → lee1, and lee@domainB.com → lee2.

[LeeT (Lee)]

Thanks @danb35, yes it is the simpler case

Is and “Account” the same as “User” in this context (the “account provider” seems to be fixed via the LDAP install)? So far I have mapped Alias lee@domainB.com to destination lee@domainA.com, which doesn’t work. I can’t quite seem to figure out how to do the mapping you suggest…

So far I have mapped Alias lee@domainB.com to destination lee@domainA.com, which doesn’t work.

That should work. What happens with this?

[LeeT (Lee)]

Great, I just re-tried and it did work, perhaps I just didn’t allow enough time earlier. Many thanks!
