    I have succesfully connected using DIGEST-MD5 to facebook, the code you have posted looks good. But still we need to check the contents of your SASLDigestMD5Mechanism class

    I have used the class provided in here with success

    http://community.igniterealtime.org/message/200878#200878

    Also you have to notice that in the DIGEST-MD5 mechanism you have to login with your facebook username and not with the email address. By default the facebook accounts don't have a username, you have to create one fisrt, you can check that in here:

    http://www.facebook.com/username/

    For me the solution was to not include the host part in the username when calling login() without DNS SRV and not agains the Google Talk services. This is also described in the ignite forums.

    E.g.

    connection.login("user@jabber.org", "password", "resource");
    

    becomes

    connection.login("user", "password", "resource");

    There is a huge thread at Ignite that deals with this issue. You may want to take a look at it as there are several solutions for Java and Android given that seem to work.
