Is there a way to set `admin_emails` to localhost while user emails go through `mail_server`? #5

Hi,

I am trying to get Arbiter2 (v2.1.0) to send the copies of all user mail notifications to /var/mail/root instead of a real email address, while notifications to the users should still go to their actual email address through our mail server.

Is there a way to do this? If I set the parameter admin_mails to root@localhost it tries to send this though our mail server (which is configured in the mail_server parameter in the same config.toml) which doesn't know who root@localhost is. However, if I want the user notifications to arrive at the users' mail addresses, I need to have the mail_server parameter set correctly, or they won't arrive. Is there a way to tell Arbiter to not use the mail server for admin_emails but just for everything else?

Thanks and best regards

I don't believe that this behavior is supported currently unfortunately. I don't think this would be very hard to implement, perhaps another mail server entirely for the admin emails could be added as a configuration option. I will take a look and see about the feasibility of adding something like this.

If you are running an MTA on the same host as arbiter (as it appears you are if you are mailing root@localhost), it may be possible to configure forwarding to different addresses there. This would just translate to the local MTA being used as the mail_server in the arbiter configuration, and rules to forward all emails but the admin ones to the regular mail server. I am by no means an expert on this, so please let me know if I am missing something.

I now just made a script that moves all the arbiter mails to a specific folder in the admin mail account, so it doesn't spam the inbox ;-)
