Hi,
I have a client that will use Office365 for it’s e-mail, but for the printer i’d like to use mailcow.
For now the mail runs on my DirectAdmin server, and i want to test to sent a mail from mailcow:
printer@clientdomain.com –> i created this one on mailcow
And from that e-mail i try to sent an email to info@mydomain.com –> this domain is on my Directadmin server
But i keep getting “Could not complete sender verify” eventho i did apply ;
Relay all
DNS ;
DKIM and SPF
What did i do wrong?
