Hi Grant,
I just wanted to let you know I got this forwarding now working on mx and do not need to route first to out any more.
I have removed the mailhost from ldap routing.
mailLocalAddress: test@me.com / test@example.com
mailHost:
mailRoutingAddress: test@guerrillamail.com
Currently I am only rewriting the envelope. If I forward to an address of https://appmaildev.com/en/dkim
The test results show nicely everything green for spf, dkim etc.
I am doing this in the milter available on mx and the only extra overhead I have, is having to do an mx lookup to determine if the email is to be delivered external.
Would you know of something I could pass as a macro to the milter that would show if ldap routing is applied/active? If I know this, I could limit the amount duplicate dns lookups quite a lot.
