When processing E-File returns for individuals, we are receiving this error message: 

Your request was not understood by the e-filing service. - Invalid XML. cvc-pattern-valid: Value '[email address removed] ' is not facet-valid with respect to pattern '[\w\-\.\+_$&]+@([\w\-_]+\.)+[\w\-]{2,}' for type 'EmailAddressType'. Please verify that your application program is up-to-date.

The E-File does not process.  Any solutions out there?
