Hi, I have installed virtualmin on centos everything is working fine, but I am not able to go to https://domain.com:20000 for email i.e. I am not able to access email. I am able to send email from the virtualmin/webmin but I am not able to receive any emails. How do I access the webmail i.e. https://domain.com:20000 and how can I receive emails? Thanks for your help in advance.

What's the output of this command (as root)? 

netstat -plutn | grep 20000

Do you have a firewall enabled? If so, have you checked that the necessary ports are open?

Thanks for your reply @Pablo.
Port 25 is open that I have checked through telenet, how do I check whether firewall is enabled? from webmin >networking >linux firewall it seems to be enabled but I'm not confirm.
Is there any thing that needs to be checked @Pablo

@shyamsukhamit: Do you have proper MX records on your domain name?
Reply
shyamsukhamit August 6, 2013
ns1.domain.com. with priority of 5 is the only MX record I have.
Do I need to put anything else?

Try waiting a couple of hours for DNS to propagate and try sending an email again.
Do you have an A record for ns1?

No I don't have A record for ns1 in my DNS panel. Do I need to create?
Reply

Yes, you have to create an A record to that ns1 resolves to your droplet's IP address and therefore allowing it to accept mail since the MX records point to ns1.

I would like to inform you that ns1 is my host name, is it good to create an A record with that?

thanks @kamal it is working now

Yes, it's actually recommended to create a DNS entry for your hostname.

Should I add the A record, MX & other thigns for every addon domain ??

@shyamsukhamit: Yes, you should add them for every domain.

Reverse IP/rDNS is automatically set to your droplet's hostname on our control panel.

As for SPF records, take a look at this article: https://www.digitalocean.com/community/articles/how-to-use-an-spf-record-to-prevent-spoofing-improve-e-mail-reliability
How To use an SPF Record to Prevent Spoofing & Improve E-mail Reliability

A carefully tailored SPF record will reduce the likelihood of your domain name getting fraudulently spoofed and keep your messages from getting flagged as spam before they reach your recipients.
