Domain backup
Question asked by Sabatino - 6/18/2021 at 3:34 AM

I am perplexed

I've been using smarteremail for a while now and I find a lot of features that are useful to me, but every now and then I find some things that I miss compared to other mail servers. Smarteremail is very configurable and I think some things should be added.

Here is the scenario I can't replicate with smarteremail


Domain xxx.tld

manages
user1@xxx.tld
user2@xxx.tld
user3@xxx.tld
user4@xxx.tld


For line speed needs, the customer decides to install a version of smarteremail on a local server but which he will only have to manage

user1@xxx.tld
user2@xxx.tld

Basically it downloads the messages from the main server with remote account for user1 and user2

What happens if user1 decides to send a message to user3@xxx.tld


With other servers I had the possibility to set the local server as a backup, set the fact that if a message is sent to an unconfigured @ xxx.tld user it must forward it to another server
mx.xxx.tld

And this happens at the SMTP level. Using the catch all addresses would become all complicated and in any case it would not work correctly if the destination addresses are more than one or even in bcn

Here is a typical configuration on another server

I assure you that I have been using it for years and it works great


In practice it behaves like this
If it finds a user locally, it delivers the message, if it cannot be found it forwards it to another server

Hi xabaras, 

Depending on what version/build of SmarterMail you're using you can do something similar. SmarterMail has a feature where you can select if delivery should be local or external (using MX records or a host address). You'll find this setting when you login as the system administrator and edit a domain, Configuration tab > Email card.

  • Inbound Message Delivery - Administrators can specify the domain location for incoming email delivery. This allows you to specify whether the domain is hosted locally or partially/entirely on an external server. The following options are available:
    • Local - Select this option if the mail server is hosted locally.
    • External (use MX record) - Select this option if the mail server is hosted partially or entirely externally. Messages will be delivered based on an MX lookup. Select the option "Deliver locally if user exists" to perform a local delivery instead of external if the user exists locally.
    • External (use host address) - Select this option if the mail server is hosted partially or entirely externally. Messages will be delivered to the specified host address. The host address can either be entered as an IP address or the Fully Qualified Domain Name (FQDN), such as mail.yourdomain.com. Select the option "Deliver locally if user exists" to perform a local delivery instead of external if the user exists locally.

Thank you
It seemed strange to me that it wasn't there.
I have tried and it works fine.
I keep studying

Thanks again
