In addition to Eric's suggestion of ensuring DNS records are pointing
correctly, check that the server you are using to send mail with (The
External server you mention) is not also set up to think it handles the
mail for your domain locally. If it is, it won't even look at DNS.
This is especially likely if this server USED to host your mail, and you
simply put up the QMT, and re-pointed your MX record to it, but did not
remove the domain from the External server's Localhosts/rcpthosts/etc
file, depending on the flavor of the external mail server.
This issue will result in inbound mail from The Net being properly
delivered, but mail sent via the External server not being delivered.
This includes anyone else using that Hosts servers to send mail. This can
be hard to get a large host to correct, since Tier 1 support will usually
not grasp the issue.
Also, this issue will not cause the mail to be bounced if the e-mail
accounts are still on the External server, since they are being delivered
locally... You might be able to log into the External mail server via a
webmail client or something on THAT server, and see the mail...

account, but when I look at the logs there are no entries for these
message
ever getting delivered.
Is it possible we are rejecting messages that do not appear in our logs?
Could that be messages that don't get in the door? If so is there a
level
of log we can put in place to see these messages.
It's just a bit embarrassing, as the mail manager not being able to work
out
what is happening. So any information would be appreciated.

I don't believe a message would be rejected for any reason without a
message being written to the smtp log. spamdyke logs from address, to
address, and sending server's ip address in all rejection messages.
Older QMT versions that rejected due to SPF would not log a message to
that effect, but there would still be a pid from message in the log.
That's been fixed for maybe 2 years or so though.
If there's no indication of the message reaching your server, I'd
suspect a misdirected DNS record of some sort.
