Sending Mass Email By a Third Party-Blocked

A company that I support is using a third party company to mass email for them.  Now the email is sent daily as: today@acme.com. This email is supposed to go back to the office manager at Acme.com, so he can monitor the emails.They should be emailed to his account joe@acme.com. I tested the account and emailed him internally and externally from the account:today@acme.com it worked fine.
What is happing is the emails are being blocked from this company and not going to the office managers  account.  I did whitelist the address in the TrenMicro Spam virus server.
All I can think to do is have them create a SPF record on their servers and bypass the Acme.com Exchange server. This company also houses  Acme.com`s DNS. Am I correct in my assumpption?

SPF should not be a hard failure item, its level of use it is not enough to do that.
SPF records will not do any harm, but you need to liaise with the third party to ensure that you do not block those email messages.

Have you actually verified why the messages are not coming in?

If you are referring to SPF record creation, you need to ask them what to put in to the records.
However unless you are using SPF records yourself, setting them will not help.

As I wrote above, you need to discover why the messages are being blocked. If the problem is with your software then something should be logged.

This is an idea what i am getting.

Hi. This is the qmail-send program at mail1.non.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

That is not an Exchange message. The message is being rejected by the remote server for some reason.
The logs on the sending server may tell you what IP address the connection is being made to, which will be the server rejecting the message.

What I think that is happening. If you send a email form another Server saying; You are Acme.com,
and forward it back to the "Real Server" that server will reject it ,because it knows you are not Acme.com.
Am I right?

The error tends to point to it being a Recipient error, not a sender error.
The usual reason I see this is because the host thinks it is responsible for the domain, rather than an external service. Many ISPs and hosts are setup so that they presume they are responsible for everything - email and web. The domain is in their local hosts table so doesn't even query the MX records. That is why knowing the IP address of the server that it is trying to connect to would give you an indication if that was the case.
