But with DiscussionPlugin, it leads to a failure to post to a forum with the following error : {{{ Trac detected an internal error: SMTPRecipientsRefused: {u'emailAddress=jouvin@lal.in2p3.fr': (550, '5.1.1 ... User unknown')} }}} It would be nice if the plugin could check the userid looks as a valid email. In particular something like a certificate DN is easy to identify as it contains / and = that are invalid characters in an email adress. It'd be better to be able to parse such a userid and look for emailAddress if present (not necessarily the case) but this should probably be handled by Trac notification system itself.
