Email setup on VPS

[distro]

So, i have setup email system on my VPS. I can't send/receive internal emails and cant send/receive any other provider emails.

I registered a domain at .tk and pointed them to clouddns nameservers.
At clouddns.net system I have setup A record, NS record using nameservers of clouddns,MX record for mail.blah.tk and pointing to www.blah.tk
Another txt record added, for mail.blah.tk and pointing to my server ip.

Anything else should I do to solve this ?

 

[distro]

the email address on my system are as test@mail.blah.tk
The email system shows "message successfully sent to blah@yahoo.com" but doesnt reaches me.

You need to check if the IP Address of your VPS is on the black-list. There is typically a "reputation" of sorts for each IP Address that determines whether or not email servers block the incoming emails from those IP address or let them pass.

I sorted out the problem by:
1. bypassing clamav check, dont know why but clamav was failing. I think its the low RAM.
2. setting up proper MX record
3. disabling greylisting.
