Can anyone please help me in this? 

Can anyone please help me to figure out how can I receive offline messages from ejabberd server (installed on ubuntu server)?

I am very new to XMPP. I could not find anything helpful while searching for few days on google. Can anyone PLEASEee suggest me what should I refer for using XMPP with Python?

Thanks in advance.
