To be clear, having the nonexistant in both systems users just disappear is fine with me. "Fixing" that is not a priority, but making the split domain setup be less of a pain to manage (having to add Google accounts in both places, with Postfix transport map set to force them to Google via MX if it

MX only points to Google on this domain that we want to set up this split domain handling. The other domains' we have configured in Postfix, their MX only point to Postfix. In all cases, MX only goes to one or the other. Google DOES accept mail for invalid recipients, and then relays them to Postf

We receive mail directly from the internet, but not for this particular domain. This postfix also handles virtual mail for domains that aren't on Google apps, this is the only time it's listed as the MX. The only time it receives mail from outside our networks on this domain is if Google Apps is r

Google Apps handles our mail, and relays any non-existant accounts to our Postfix server. This works fine, and we can then use virtual accounts on our Postfix server to do whatever we wish. However, we have a problem with relaying mail from inside our LAN through our Postfix server to addresses at

Split domain configuration w/ Google Apps

2015-03-16 Thread Jonathan Vaughn
I'm trying to set up a split domain setup with Google Apps. Google Apps has the rather neat option of sending mail on to your own SMTP server - it can send all, or just those that aren't delivered in Google Apps (i.e. no mailbox/mailing list exists for that address). We have configured it to send u
