User development, A new message was posted in the thread "Unable to set the mail configuration properties in JBPM 4.0": http://community.jboss.org/message/521088#521088 Author : Ronald van Kuijk Profile : http://community.jboss.org/people/kukeltje Message: -------------------------------------------------------------- This one looks (almost) fine.   If you want to send task notifies and reminders, you need a mail.from or mail.smtps.from to. If that is not present, I think javamail will concatenate the user and host so you'll get a   mailto:xxxxxxx95@tifr.res.in@mailhost.tifr.res.in   which is incorrect and not sure if that results in the same exception you got before (I think it does).   So e.g. setting   mailto:mail.smtps.from=noreply@tifr.res.in   is always a good thing and will be overridden by the from you set in the mail nodes -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521088#521088
