MIcrosoft Exchange 2003 expert needed

I need an expert in Microsoft Exchange 2003 to fix some errors.

Also the exchange server rejects some email and also has issues sending email. The problems started after I hired someone to snyc our iphones to our exchange server.

Here is a typical error we get back when we send email to some people outside our network:

[url removed, login to view] #5.5.0 smtp;554 Service unavailable; Client host [[url removed, login to view]] blocked using Barracuda Reputation

Here is another error message

Could not deliver the message in the time limit specified. Please retry or contact your administrator.

<[url removed, login to view] #4.4.7>

Another error message
