Hi,

I would like to send some emails with a relay host, depending on the recipient email.
For example, every @hotmail.com or @outlook.com would go through smtp.provider.com, the rest can be send directly through iRedmail server.

Is it possible to do that?
Is it supported with the Pro version?

Thanks...

Re: Recipient dependent relay host

Are you refering to "docs.iredmail.org/relayhost.html" and "docs.iredmail.org/per-account.transport.html" ?

If yes, then I dont want to do that. As far as I understand the doc, it uses a relay based on the iredmail sender email or the sender email domain. Unless I misunderstand or missed something.

For some accounts, I want to send emails to a specific relay based on the recipient domain outside of iRedmail. When a iredmail sender email account send an email to a gmail.com address, I want iredmail to relay through smtp.provider.A.com. When a iredmail sender email account send an email to an outlook.com address I want iredmail to relay though smtp.provider.B.com, and so on...

Thanks...

Re: Recipient dependent relay host

it is in transport maps, so you can map a whole domain to an external relay
