I was checking my config of my spf record because gmail email addresses are being placed in the spam box.
I have solved many errors but I cannot fix this one
this is my error
The SMTP server does not accept mails to postmaster@[IP_ADDRESS]. This is a very bad thing, as this address is used by people that don't know your domain name! The reported error is: 554 5.7.1 <postmaster@[IP_ADDRESS]>: Relay access denied
IP_ADDRESS is my IP
can anyone help me how to get rid of this error
and this error
SMTP Banner Check Reverse DNS does not match SMTP Banner
how to get rid of this error
kind regards leon
