在joomla的KUNENA扩展中由主持人批准主题设置电子邮件收件人

This site is not developed by me and I have little knowledge in joomla

Site type - forum
Platform - joomla 1.7.1
extension installed - Kunena 1.7.0

Process :- When a topic is added to a category by user, then this topic should be approved by the moderator of that category

and moderator can approve the topic

Now when a topic is approved by a moderator following mails are triggering

  1. A mail to the Moderator(in Inbox) OK
  2. Super Administrator(in Spam) Should be in Inbox
  3. A Mail delivery failed mail to the user who uploaded the topic as below

enter image description here

My main problem is how to send mail successfully to user on approval of his topic

Please go to Configuration->Security and then setup E-mail Moderators to Unapproved Posts

Then You should setup all categories with approve post by moderatores
