Here I thought I was finally starting to understand this. :( At least
the DNS part was right.

I'd like to know if this works, but I don't expect it will.
I believe that chkuser is not finding an MX record for the
backup.mydomain.com domain, and this cannot be specified in the hosts
file. An MX record for backup.mydomain.dom would need to be added to
the authoritative DNS for the mydomain.com domain. While this would
fix the problem, I don't think it's the best solution.
Fixing the problem at its source is preferable. (more on that elsewhere)
Like the tcp.smtp file? Did you see the other comment by Andreas? Is
that a valid fix?

Mike,
I am not 100% sure, but I think you can put the MX address in the
host file of the server that is rejecting the mail because of an
invalid sender MX domain. I am pretty sure it's because it can't
resolve the address.
Host file entry
<snip>
77.60.23.95 backup.mydmain.com
</snip>
or you may be able to add an entry in the local domain file.
I believe either solution will work. Hopefully someone else can
chime in to confirm. I don't think the rcpt host file allows ip
addresses.

To All,
I now have in place three Qmail Toaster Servers in three different
locations. These servers are part of individual networks, or whish
there
are other CentOS and RedHat servers.
I am having issues with mail from the other servers as these are
running
Sendmail by default. The problem lies in the fact that I can send
messages
from the Sendmail servers to the Toasters Servers, as long as they are
within the same network and they are not an alias/forward account.
The real issue is CHKUSER does its job too well and it rejects
messages from
the Sendmail servers, if it's to be sent to another account or network.
This is the type of error I get...
@400000004ae9186406b54edc CHKUSER rejected sender: from
<r...@backup.mydomain.com::> remote
<backup.mydomain.com:unknown:77.60.23.95> rcpt <> : invalid sender
MX domain
I understand that there are issues with servers that are not really
configured as a full Mail server, but what can I do to rectify this
error.
Can someone please let me know what I need to do to the sendmail.cf
file to
get around this. Or what needs to be done to the Qmail Toaster
settings to
allow the "incorrect MX" issue.
Cheers
Mike Canty
