Hi All
A little background on our setup and how we manage our domains.
We currently have our @greenpeace.org MX records pointing to Google as we are using Gmail as our core email handler. This is historical and has been in place for many years (decision I was not involved in)
As we also operate sailing vessels that require email to be replicated on board to allow access in offline situations and queue emails ready to be sent once connection is restored, this is due to limited/ intermittent satellite connectivity while at sea.
We run Nethserver on board all our vessels. With another delivery service in between GTmail (from GTmarine) that will do compression on mail before exchanging between shore and vessels.
Nethserver is configured with a local domain @ship.greenpeace.net but also set up to be able to send and receive from @greenpeace.org addresses.
What we are seeing here with Nethserver 8 is because we set @greenpeace.org as another domain on the vessel it thinks it is authoritative for @greenpeace.org.
For example we have the following setup on the on board Nethserver
ship.user1@greenpeace.org
ship.user2@greenpeace.org
ship.user3@greenpeace.org
Emailing those addresses locally is fine with mail being delivered fine to those addresses
but when we want to send an email from the vessel to shore side staff
For example
office.user1@greenpeace.org
office.user2@greenpeace.org
office.user3@greenpeace.org
Email bounces as Nethserver cant find it as those office users as they are not defined locally on the vessel’s Nethserver.
On Nethserver 7 this worked fine for delivering mail locally to those addresses that were defined on board and for those addresses that were not it would use the “Relay to another server” setting that was define on @greenpeace.org
We already have the the following relays set in NS8 for testing but we still get a bounce.
Also a details diagram of our mail flow for our vessels.
Perhaps we have a niche case here and might not be configurable in the UI but perhaps in some config files we could amend. Just as i was getting my head around e-smith templates too.
Happy for any input and more Simpsons references warmly welcomed.
Thanks again for the support.
