i can send but can't receive mail
i have centos 64 on linode .i am using postfix and dovcot .although everything seems okay i can send emails but unfortunately cant receive any.what may be the issue?
any help is welcome
If you aren't having any other networking issues and you haven't changed the email port , it sounds like this might be an issue with your firewall configuration. I recommend that you check your ports, and iptables with the following to help identify the issue:
From a local host
$ nmap $IP
On your Linode
$ sudo iptables -L
