Reverse DNS does not match SMTP Banner

email

Hi!

I have setup rDNS by following the instructions in the Linode library. However, when performing a smtp test on MXToolbox, I'm getting the error Reverse DNS does not match SMTP Banner

Have googled it and most comments is "Contact your ISP to solve this problem".

How do I solve this? Thanks!

By the way.. The PTR seems to work fine. My linodes ip resolves the hostname (fqdn), and the hostname (fqdn) resolves the ip.

I'm an idiot.. Had missed ONE letter of the sub domain in the spelling of myhostname setting in Postfix :)
