Exim error - Mail failure, no recipient addresses

I am new, I have a problem with emails sent to my account.
All email are formatted in this way:

Mail failure - no recipient addresses
Mail Delivery System [[email protected]]
A message that you sent using the -t command line option contained no addresses that were not also on the command line, and were therefore suppressed. This left no recipient addresses, and so no delivery could be attempted.

And more stuff...

I'm not a developer, the guy who programmed the php script wrote a class that send the mail from site, but not tested on Exim...

Where I can start to solve this issue?
Thank you!
