[Pki-users] SMTP-authentication on email notification in pki server

Hi , I am using pki dog-tag package to provide digital certificates in the local network. I have followed the redhat-cs documents to configure the email notifications to send the email-queue notifications. However my email server requires "*SMTP authentication*". But i cannot able to do SMTP authentication in pki-console page and cs.cfg file. Please assist me to configure the "SMTP authentication" in pki-console or in cs.cfg file. Here my system specifications, OS = fedora 10 pki = dogtag localmailserver = sendmail Waiting for the reply asap. Thanks, Jagan.k --
