« on: November 05, 2019, 10:35:21 PM »

This is a test from appmaildev.com:

SPF: Pass.
DKIM :Pass
Dmarc: Pass
PTR:Exist Record
RBL: not listed

rDNS : Ok
MY  server  IP is clean and not listed on any blacklist

In gmail i get this :

Code: [Select]
This is the mail system at host myhost.host.com.

be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.
