Oud Of Office auto-reply doesn't respect transport settings

jwegge opened this issue 10 months ago · comments

When using a filter created in round cube (such as out of office) on a setup where all outgoing malis is sent through an external server ("Relay outgoing email to" in web front-end), this is not done for the reply generated on the server itself.

Detail: we use Proxmox mail gateway for in- & outgoing email.
Iredmail is configured for all hosted domains to use the external mail gateway (in my case 10.10.10.14:26).
All outgoing email is scanned by the Proxmox mail gateway EXCEPT for the "out of office" messages, which get sent directly by iredmail to the destination mailserver.

Destination mailserver may or may not accept these messages as different pub ip & hostname as the expected mail gateway (dkim & spf gets mangled).

Yes, because it is an autoreply, it strips out sender and other stuff to avoid bounceback loops, and aswell doesn't send trough normal sasl authenticated domain settings

consider it as an advanced bounce message

I understand, but this makes it unusable in environment where autoreply needs to follow dkim, spf etc when this is handled by an external mail gateway.

you can manually add a virtual transport map for such things

A hint as to how to accomplish this?

Working with sender_dependent_relayhost_maps and adding a "postmapped" file containing data underneath didn't work out.
127.0.0.1 10.10.10.14:26

Obviously the mysql "SELECT relayhost FROM sender_relayhost;" gives 10.10.10.14:26 for all hosted domains.

Hi, I'm looking at the same problem as well and I just discovered that the autoreply mails are not using the local Postfix instance. The e-mails are sent directly to the destination e-mail servers. So Postfix virtual transport or transport maps will not help.
Is there any way to send those autoreply e-mails to a relay host as well?

Thanks,
