Hi devs, I saw the release note of xe 1.6 http://www.xwiki.org/xwiki/bin/view/Main/ReleaseNotesXWikiEnterprise15, which says 1. Mail sender plugin now supports SMTP authentication But I can't config it in the xwiki administration. Any one can tell me how to config stmp username and password? 2. UTF-8 characters are now all correctly rendered in PDF exports I add some Chinese in a xwiki page, and export it as pdf. However, the Chinese characters still are ???. I see some fonts are added to xwiki. Can I use other fonts by config something? Thanks. Sincerely, Wang Ning
