Problem using the PDF Printer driver in LC ES 8.2

Hi all,
I have a problem making the PDF Generator Printer driver work. I am able to print a document, and it is successfully converted to pdf, but the send email service fails. The error message is:

2008-08-27 15:22:21,671 INFO [com.adobe.ipp.pdfgclient.ResponseGenerator] ALC-PDG-006-017-Refetched the email configuration details from provider.email_sendmail_service after 5 minutes.

I tried with two different mail servers, with same result. I have configured both EmailService: 1.0 and SendEmailService: 1.0 . Has anyone encountered this error before?
