Hi,
MXToolBox reports that our reverse DNS does not match the SMTP Banner even though it should.
I've made the following changes:
Exim configuration:
Send mail from account’s dedicated IP address: Off
Reference /etc/mailhelo for outgoing SMTP HELO: On
Reference /etc/mailips for outgoing SMTP connections: On
/etc/mailips:
/etc/mail_reverse_dns:
/etc/mailhelo:
When trying to telnet, it reports the correct hostname:
What could the issue be?
