Email sent to gmail is marked spam (IP listed in CBL)


I am on a Ubuntu VPS. Emails sent to gmail is going in to the spam folder. And some mail clients even won’t receive it even to the spam folder :(

My “/etc/hosts” file looks like this ocr ocr localhost localhost.localdomain ocr

Please help me to resolve this issue

Regards, Upul.

edit /etc/postfix/

find the line that says

mydomain = localhost


mydomain = localhost.localdomain

edit it so it says your domain. In this example, let’s say your domain is

mydomain =

restart postfix

service postfix restart

and you should be good.
