When case is logged from email, Notification email is received to the person who logged the case. This notification mail is sent to user with help of workflow which uses standard template. As per my requirement i replaced standard template with custom, as such to embed related article list code in custom template. The embedded related list articles are searched corresponding to subject of the case posted while creating case from email. Everything works fine with test mail. But as soon as try to log case from email id. notification mail fails. I am using to search all the relative article. Any help regarding mail failure will be appreciable. Thanks in advance.
