You need to list all the modifications and post the new config files. We can't evaluation the guide only as you might miss a step and end up with errors.

I have already resolved this problem yesterday. And emails are working fine so far, no more errors and no emails getting missed.

I had used same topic description into another forum for help also. Because that was enough for understand. I had added main.cf, master.cf and mail.log and problem was about email error in mail.log , Where some emails wasn't getting received because of finding no destination host.

What I had to do to fix it?.

Answer: I needed to include cpanel.mainwebhosting.com in line mydestination for /etc/postfix/main.cf


Hopefully this may comes in handy for other
