Hi,

I installed a new server with iredmail (because i have to working servers and love iredmail).
After installing i setup dns A record Mx record dmarc domainkey.
When i send a email to the server i never gets delivered.
When i send a email from the server email also not get delivered.

When i open the logs i get  :

(I changed the emails adres to something non real )

As you can see the emails where received by the server but i think he deletes it.

If someone could help me with this i would be very happy .
