Eric,
You are correct in the fact that the host file did not fix the
issue. Neither did adding the IP to the tcp.smtp file change. Like you
suggested, fixing the problem at the source is preferable.
Can you suggest what needs to be changed in the sendmail.cf file, or should
I be changing to postfix, as suggested by some others?
Please let me know, and keep those suggestions coming.
Cheers
I looked at sendmail quite some time ago. It reminded me of assembler
macros on a mainframe. Big turnoff there. ;) It's no wonder why it had
so many problems in its earlier years. I chose at that time to use
postfix in place of sendmail whenever possible, and haven't seen any
sendmail since.
I imagine there's a way to make sendmail do what you need, but I don't
know of it, as I don't do sendmail. I would go the postfix route, and
recommend you doing so also.

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)

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
