I was very much in doubt if I was doing something wrong when setting up the "saslauth" part. The comments at the bottom of the page saies that I would fuck up if I followed the guide. There is no answer to the comments from Falko, only from an Anonymous person. I followed the guide fully and I got a working system, but I can't help thinking if my problems was caused by the "saslauth" part or if it was something else.
If you read this Falko, then please consider to reply the comments on page 4. Your comment on this is quite valuable to new installees.
