Cannot receive email - User unknown in local recipient table

A hint, like Nuxwin said - Sendmail :P.

I-mscp install sendmail ?

I'm pretty sure it's installed as default on some debian machines, all depending on your selections during installation. And if it's a VPS they prob. use a standard mirror with sendmail as a standard package.

The sendmail MTA is installed with many openvz images. I ran with such problemes with many users during support sessions...

That most certainly seems to have been the case here.

Thank you! I seem to be turning blind. I missed that line in grep!

Removed sendmail, updated i-mscp, and now smtp service is running. So we're back to the initial issue. Mail sent from the server goes through fine. But the server cant receive mail.

Code

1. Delivery to the following recipient failed permanently: [email protected] details of permanent failure:Google tried to deliver your message, but it was rejected by the server for the recipient domain joel.co.in by r2d2.joel.co.in. [50.7.228.37].The error that the other server returned was:550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table

Dig of my MX record yields this:

Code

1. joel.co.in. 14400 IN MX 10 r2d2.joel.co.in.

The FQDN of my server as set on the VPD panel is r2d2.droidzone.in. Is this what is supposed to be set up?

Other records are as follows:

Is there a mistake somewhere?

Latest mail logs are again uploaded. I've got to solve this somehow.

Are PTR records essential? I've submitted a request to my VPS host to turn on rDNS for me, but apparently the request needs to be sent through their main data centre to get activated.

My postfix config:
main.cf

Hello ;

Well, you are using openvz or something like this ?

You must kill and purge the sendmail MTA packages and rerun the i-MSCP installer.

I can assist you via teamviewer if you want. Just PM me

Thank you for using i-MSCP.

Yes, Nuxwin, my VPS control panel is Solusvm. However I have removed sendmail:

Code

1. sudo apt-get purge postfix exim4 sendmail sendmail-bin

And reinstalled i-mscp. Now, sending email works and smtp is shown as active. Once again, I cant receive email.

Are you sure that the sendmail MTA process is not there ? Sometime, only a purge don't really stop it... Stange but true...
