Is there any documentation of how the add-on works and to trouble shoot the problem?
1) My Mail_Doc cannot send an email, I got the mssg that email being sent successfully, but when I check my email, it seems that I never get it? What things I should check to make sure that I configure it properly?
2) How the ado_search works and how to configure it properly?
3) Also, what is ShortList module and how it works?
Thanks in advance.
