How to fix the “federated domain” problem in emesene

If your emesene keeps displaying the annoying message “User could not be added: Email Domain is IM Federated Contact LiveID xxx@yyy.com is federated domain.” no matter if you accept or reject the user, then you probably want to apply this patch.
This is not really a fix, but a workaround, is just a hack to avoid displaying the error message if you really like emesene and you want to use it. If you don’t like this kind of ugly solutions, there are always other options like Pidgin, aMSN, etc. — in other words if you don’t like programming forget it, or wait for a new emesene version.

Ok, so, since we have the source code (emesene was developed in python) the file we need to hack is /usr/share/emesene/Controller.py
We just need to find the two lines that displays the messages, and bypass them if the user is our xxx@yyy.com. That would be (in the current version as 2011/03/30) lines 674 and 770.

in line 674 add:
if mail in ("xxx@yyy.com", ): continue

then in line 770 add:
if email in ("xxx@yyy.com", ): return

So the final Controller.py will look something like:

....

    def checkPending(self):
        '''Check for users pending to be added'''

        if self.msn is None:
            return False

        if self.addBuddy is None:
            self.addBuddy = dialog.AddBuddy(self)

        users = self.msn.checkPending()
        if len(users) > 0:
            for mail in users:
                if mail in ("xxx@yyy.com", ): continue
                nick = self.msn.getUserDisplayName(mail)
                self.addBuddy.append(nick, mail)
        return False


....

    def addNotification(self, msnp, command, tid, params, email, nick):
        '''this method is called when a user adds you'''

        if self.addBuddy is None:
            self.addBuddy = dialog.AddBuddy(self)
        if email in ("xxx@yyy.com", ): return
        self.addBuddy.append(nick, email)
