Howdy -- it sounds like emails sent to postmaster@securemailsender.info are being delivered to the address admin@securemailsender.info -- but it sounds like that admin@securemailsender.info may not be working.
Can you verify that your system has the "admin@securemailsender.info" email address setup?

One thing that could cause a problem like that is if your systems hostname is the same as a Virtual Server that you have setup on your server.
That is, if you run the command "hostname", what output do you receive?
If that output is a domain on your system -- you may want to change your hostname. If it's not already, I would recommend making your hostname an FQDN, in the format "host.example.com".
If that doesn't help -- I'd be happy to log into your system to take a look.
You can either enable Remote Support, using the Virtualmin Support module, or you can email me your root login details at eric@virtualmin.com.

I'm noticing two main issues there that are likely to contribute to that.
One, it doesn't appear that your system's hostname is listed on the "mydestination" line in your /etc/postfix/main.cf file. Without that, Postfix wouldn't understand how to deliver messages locally in all cases.
Two, there isn't a DNS 'A' record added for your system's hostname. I'd suggest going into Virtualmin, and in the domain "securemailsender.info", I'd go into Server Configuration -> Edit DNS Records, and add an 'A' record for "host.securemailsender.info".
Also, I'd suggest adding a DNS 'A' record for ns1.securemailsender.info and ns2.securemailsender.info.
However, even without that, once I added your hostname to Postfix, I was able to send a test email to an account on your system. So once you tweak the DNS, that should resolve the issues you're seeing.

Hmm, it looks like your other server was changed to use Sendmail, rather than Postfix. In general, unless you really need Sendmail for some reason -- I'd recommend using Postfix, as Sendmail is much more difficult to configure, and most of us don't know it very well :-)
It doesn't look like you have many users setup yet, so if you can, I'd suggest moving back to Postfix (which will require re-adding any users and aliases you already have setup).
If you do that --
It looks like Postfix has the same issue on the new server -- in your /etc/postfix/main.cf file, there's a "mydestination" line -- and that doesn't contain the system's hostname, "host.bresponder.info".
My recommendation would be to edit that file, and add your hostname to the "mydestination" line.
When you're done, restart Postfix with this command:
/etc/init.d/postfix restart
After that, email delivery should work correctly.
