Multi E-Mail Addresses

Quote from UncleSam

Ok I tried what you said:

- Changed my mail account from mail to mail+forward

- Added onw forward address to the list called "testaddress@domain.tld"

- Send a mail to "testaddress@domain.tld"

- Got error (User unknown in virtual mailbox table)

Basically, what you want is ability to send mails to aliases in which case, the mails should be delivered into the mailbox of the mail account for which you have defined them. Problem is that aliases don't always belong to locally hosted domains.. You can have an alias address such as user@gmail.com ... But I'll check the behavior and see if we can add specific "rules" for aliases that belong to local domains. By local, I mean those for which domains are hosted locally. In reality, those are virtual domains...

Right now, when creating a normal + forward account, we end with something as follow (alias map):

Here, any mail sent to the whatever@bbox.nuxwin.com mail account would be:

1. Delivered to the whatever@bbox.nuxwin.com mailbox
2. Forwarded to the alias@bbox.nuxwin.com alias

This is the current behavior but you, you want also be able to send mail to aliases:

This is the same as above but with another alias entry. Mail sent to the alias@bbox.nuxwin.com would be:

1. Forwarded to the alias@bbox.nuxwin.com

You see the problem here? This create a loop and you would end with a "loopback to myself" error:

Mail sent to alias => forwarded to whatever => forwarded to alias => forwarded to whatever... (LOOP)

I've just made a test with the following entries:

This seem to work as expected (no loop).

Below the SMTP session (sending mail to alias@bbox.nuxwin.com which is an alias of whatever@bbox.nuxwin.com :

Note: Don't pay attention to the warning regarding TLS... (self-signed cert)...

As you can see, the mail sent to alias@bbox.nuxwin.com (alias address) has been delivered into the whatever@bbox.nuxwin.com mailbox. This is what you expect. My thinking is that this would cause a loop but it seem that not the case... I need to do more tests to be sure but if that still OK, I'll improve the feature, automatically adding required entries for aliases (when those belong to a domain that is hosted locally).
