Ask: Multi-Domain Support? #36

Closed cremesk closed 5 years ago

cremesk commented 5 years ago

What do i need for Multi-Domain Support? It is nesessary to modify '/etc/postfix/dmarc_transport' with the following content?

hostmaster@domain1.com  dmarc-rua-parser:
hostmaster@domain2.com  dmarc-rua-parser:

Thanks!

@cremesk yes, you need one entry per email address you defined in your DNS records.

You may also only have one mail address to receive reports, but you must define in your receiving domain the domains for which you are allowing the receipt of reports . For exemple :

/etc/postfix/dmarc_transport

hostmaster@domain1.com  dmarc-rua-parser:

domain2.com DNS records:

_report._dmarc.domain2.com.           TXT          "v=DMARC1; p=quarantine; pct=100; rua=mailto:hostmaster@domain1.com; ruf=mailto:hostmaster@domain1.com"

domain1.com DNS records:

domain2.com._report._dmarc.domain1.com.                 TXT           "v=DMARC1"
