1. Why is it reporting panel.mydomain.tld as mail server when all my DNS settings are mail.mydomain.tld ?

2. I created both abuse@ & postmaster@ email addresses, thought that would fix error ?

3. My TLS report is all good |Green OK| but still not able to send emails out. (recieving ok)

4. DMARC is not configured ?

If I find the answer else where i will update this thread so it helps the new people trying out Sentora for the first time. Hopefully they will stick around and become loyal supporters of the project

I've added this at my domain registrar DNS TXT

_DMARC TXT v=DMARC1; p=none

Seems to have stopped the error/warning
Does anyone else know the correct way to set this up ?

smtp
mail.mydomain.tld
Reverse DNS does not match SMTP Banner 

dns
mydomain.tld
SOA Serial Number Format is Invalid
 

dns
mydomain.tld
SOA Expire Value out of recommended range

ANYWAY to correct these ?
