I am struggling to configure my setup for compliance with DMARC.
My system has two domains: company.com and somethingelse.com (names changed )
My primary account = glenn@somethingelse.com
My secondary persona = glenn@company.com
both domains return valid and correct SPF, DKIM, DMARC info on mrtoolbox.com
Since I've activated the DMARC reject flag, once in a while, outgoing messages are refused by the target email server with following error:
Code: Select all
<contact@contact.com>: host mx.contact.com[xxx.xxx.xxx.xxx] said: 550
#5.7.1 DMARC unauthenticated mail is prohibited. (in reply to end of DATA
command)
One thing I see in the error message, is that, when I send as my secondary persona, the return-path still states my primary account.
Could this a reason for the rejection?
suggestions welcome
