This isn't a very efficient way to do this. You should be using
filter() not all() here.
messages = Message.objects.filter(recipient__in=['Alle', department])
Then you don't need the loop and the messagelist variable at all.
Having done this, you can just slice off the first two:
messages = Message.objects.filter(recipient__in=['Alle', department])[:
2]
Or, you could do it in the template:
{% for i in messagelist|slice:":2"%}
