emails don't reach haraka #686

Closed ghost closed 10 years ago

ghost commented 10 years ago

I set up haraka as a proxy server to a Postfix server on another machine. I understand that I have to confiigure both Haraka and Postfix to recieve emails for the same domain name. So, I added an entry in host_list with the domain name of the Postfix machine, let's say email.myexample.com.But now the emails don't reach Haraka anymore. I also understand that for an email to reach haraka a MX record must exist pointing to haraka. So maybe that is why emails don't reach Haraka. If you think that is the case, what must the MX record contain?

Ok - here's an example configuration for domain example.com:

You would add example.com into config/rcpt_to.in_host_list and set-up Postfix to accept mail for the same (you're on your own here; I've never used Postfix myself).

Let's say Postfix is running on host 1111.222.333.444 on port 25; you add queue/smtp_proxy to your config/plugins file and set-up config/smtp_proxy.ini to use host 111.222.333.444 on port 25.

Let's say your Haraka machine has an external IP address of 444.555.666.777 and it has a public DNS hostname of haraka.example.com; so you would set the MX record for example.com to:

@ IN MX 10 haraka.example.com. haraka IN A 4444.555.666.777

I should probably also mention that you don't need an MX record to deliver a mail to a hostname (e.g. host.example.com) because if there is no MX record the A record is used as an implicit MX record.

if I'm sending and email to a user from postfix @ haraka's hostname, the mail arrives in haraka and in postfix, but if i'm sending it to an user from postfix @ postfix hostname , the mail arrives in postfix but without passing through haraka.

You could therefore add an MX record to the Postfix hostname pointed to the Haraka hostname e.g.

haraka IN A 4.5.6.7 postfix IN A 1.2.3.4 postfix IN MX 10 haraka

That should work - depending on your DNS configuration...

You would also have to add the Postfix hostname into config/rcpt_to.in_host_list as well as what you already have.
