Hmmm... Since you have no log files that have helpful information, I wonder
if the email sender is actually getting to your machine. Look at the bounced
message header carefully, to see if any of your domains, show up as one of
the servers in the return path. If the message was bounced by the postmaster
at the sending domain, then its logs might tell you more about its
connection attempt (IP addresses or hostnames). Sounds to me like a DNS
problem, more than anything, but without any data, tough to back that up
(and your DNS seems to be mostly OK, see below).

In checking the domain mailroot.com, I do find that doing a DNS reverse
lookup on the IP used for the.mailroot.com, it comes back with a different
hostname. Some (especially SendMail) servers do a reverse before accepting
you email. Although this should not affect email coming to your IMail
machine/domains.

Here is the DNS data:
mailroot.com.
    nameserver = NS1.MYDOMAIN.COM.
    nameserver = NS2.MYDOMAIN.COM.
    nameserver = NS3.MYDOMAIN.COM.
    nameserver = NS4.MYDOMAIN.COM.
    10, the.mailroot.com.
    207.194.169.51

the.mailroot.com.
    207.194.169.51

51.169.194.207.in-addr.arpa.
    host = fat-static-207.194.169.51.fatwire.net.
